Happijac bunk system mods and bulletproofing

[@frankwern8784]

As a new 2022 21G owner this video was informative, thank you. On our HJ assembly the shaft has been updated. No set screw…current production the shaft is notched and a c-clip is used to fix length. Much better design.

[@terryhatfieldmin]

Thanks Frank! I saw they had updated it...finally. Glad to see them fixing some of the issues.

[@EricLakin]

I watched this video a while back, and our our 2nd trip in our 320G the damn shaft slid out on that bunk. Thanks to you I knew exactly what the problem was, and when I got home I did the locktite / hose clamp fix. Thank you for such great content.

Thank you Eric! So nice to hear the video was helpful.

Thank you Terry. Sitting at Disney camp ground and went to let down couch down and drivers side fell. Pretty sure it’s the set screw issue. Gotta wait for help to lower bed down manually but at least you got me understanding how it works.

[@EVModules]

Great tips! I've done many of the preventive things earlier, especially the screws that fastens the rails to the walls. I made new brackets for the lower bunks so they would position the bunk closer to the ceiling to give more headroom. Maybe you can try a set?

[@terryhatfieldmin]

Thanks for watching. The brackets sound interesting. I'm sure that there are people that need every inch of headroom they can get. We're fine with how ours is now though. Thanks for the offer!

[@crashweekly7925]

I just purchased a new 2022 toy hauler and the first thing I did was loctite the set screw ( still had one) on the shaft and put a hose clamp around the shaft to prevent it from sliding off if the set screw comes loose. My system actually had an extra C clip closer to the shaft as if to stop it from moving more than 1/2". I still used the hose clamp because it fit between the shaft and the clip and I don't trust a 1/16th" piece of metal stopping that heavy shaft. My next project will be replacing the self tappers with lag bolts to secure the rails better.

[@terryhatfieldmin]

Yours is the newer configuration. Definitely an improvement over how the older ones like ours were done. Nothing wrong with adding some extra insurance!

I have the '08 version Happy Jack and no problems until this year. One corner of the slider in the track would hang up then drop. A little silicon spray did the trick so I recommend that as maintenance every few years. Will be checking my set and wall screws as well. Thanks for the info Terry.

[@toddhunsicker18]

Hey Terry, my issue with my lippert bed seems different than yours…I don’t have any issues sitting on the bench with just the one leg of support. But when I have the seats all folded flat, any time someone lays on the lower “bed” it caves in on the middle. Initially when I watched this video, I thought that was what you were correcting but you put two under the actual bench. It seems to me that the solo support for each headrest of a bench s hould be installed on the other bar (the one with the zipper) to actually make it well supported. My 28G is used so I thought perhaps someone installed it incorrectly, but after watching your video and others, they come that way from the factory. So I’m thinking I will add two supports just onto beef up the two middle “lay flat” portions of the benches. 1) I’m wondering if you think it would be better to mount them on the bar of each headrest that is closest to the MIDDLE of my rig (the one that has the zipper). The only disadvantage I could see to moving them to the bar closer to the middle is that there may be issues when trying to fold it back into seat mode. I’ve messed with it a bit and don’t think it would be an issue. What do you think? 2) how many holes do you have visible on each of your support legs for the actual bench version and how many do you have visible on the support legs for the “middle” portion of each bench (for the headrest)? I have two holes visible on my middle support legs, then only one whole visible on the outer support legs (the one you beefed up).

[@terryhatfieldmin]

I would not mount the legs on the rollover section by the zipper. I think the legs will damage the upholstery on the lower section when they are in the seating position. My legs have the same hole configuration as yours.

[@chiefsartain7711]

I've been researching a solution to this issue and your questions are exactly what I'm wondering about. To put additional legs under the center portions or the bench portion. Mainly worried about mine in the bed position. It has a terrible hump in the middle.

[@stevecook7594]

Thank you so much for this overview. I just bought a 2021 21G and had concerns about the bed system. I plan to make these mods tonight! I have also already ordered two more legs for the sofas. I also plan to add the lights under the bed as well. would you be willing to provide more details on how you ran the wire from the factory light to the ones you installed? Is the wire just lying on the bed, or did you install some sort of raceway? Did you put in a plug to remove the cord if needed? Where did you drill the hole to fish the wire down? Thanks!

[@terryhatfieldmin]

Thanks Steve. The wiring is in flexible wire loom. I attached the loom to the bed base with plastic cable clamps and screws. I have a couple of spade connectors on the wires so I could remove them if needed but I seriously doubt I would ever need to remove that upper bunk. I drilled the hole just above the bed frame, directly above the push button light on the wall of the 31G. I'm not sure if that light exists on a 21G or not so you may have to find another source of 12 volt power.

Terry, you explained in another comment how you took the existing light off of the side wall and then splice the wires together from the retractable cigarette plug but my follow-up questions are: 1) how did you connect the wires from one light to another or how did you split the electrical cord that’s retractable to make sure it goes to both lights? 2) Second, after installing them I’m sure two lights makes it plenty bright but did you try it with just one light or what are your thoughts about lighting if there was just one? I accidentally ordered just one solo light by mistake and and I’m thinking of just going with one light to make things easier for myself because I’m by no means an electrician and save on cost a little

[@terryhatfieldmin]

Hey Todd. The low voltage wiring is easy to splice. I ran wires from the coiled cord to the area in-between the lights and then spliced in to those wires using butt connectors to run wires to each light. One light might be ok but I feel like having two is really the best. Here's a link to a picture of the wiring layout on my Flickr page. flic.kr/p/2nGXW7a

Could you do a video on removing the couches and modifying the lifts system to bring the bed down to a lower height, if that is possible. I personally think a separate bed room is a waste of space for 16 hours of the day and would like to make my bedroom into a storage room and laundry room.

Probably not a bad idea just for peace of mind.

Hey, thanks for this video. I had some issues with the hex rod slipping out a while back, did some "creative fixing", but your method is better with the clamp. I think you indicated your problem was the rod slid from driver side to passenger side. Mine did the opposite and came out of the motor drive receptacle. Since I didn't even KNOW there was a set screw, I guess mine fell out prior to purchase! I'll be replicating your clamp fix *and* getting a set screw in place. Then I can remove my creative "woodwork" (horrible, until I found a better solution, which I have now!).

[@goldbergdanny]

Awesome channel! I’m about to take delivery of a 2021 GD 31G to haul around my Can Am X3, so we seem to have similar intended uses. Tried to send you a direct message, but KZbin doesn’t seem to let you do that. Anything in particular I should look for/be cautious of when I take delivery and before I drive away from the dealer?

[@terryhatfieldmin]

Basically you need to thoroughly inspect everything. Make sure everything operates as it should. The dealer should have the trailer hooked to water and power for the inspection. GD has been very responsive if warranty repairs are needed but it is much better to catch anything that needs immediate attention before taking possession on the trailer. Tese trailer require a hitch that seems like overkill to pull well. I very much recommend the Weigh Safe 20k pull/2k tongue weight True Tow hitch. Do not let the dealer talk you into an inferior hitch. Our 31G has nearly 2k lbs of tongue weight loaded without the Talon. You must have a hitch rated for that. If you do Facebook we have a great group there just for the 29G and 31G trailers. I highly recommend joining. Tons of great info there. Here's the link. facebook.com/groups/momentum29g31g

My 28g is at the dealership dealing with his very issue as we speak they are not being very receptive to my issues. i took a tour through a 2021 momentum and noticed that the back beds have 4 drop down legs per side now . My dealership is horrible to deal with and basically said you are on your own with the issue. and as they were running the bed up and down in front of me to show me the $650 fix they did by adding more screws to the rails the whole left side bed fell to the ground. needless to say its still at the dealer ship.

[@terryhatfieldmin]

The bed falling is absolutely the drive shaft issue that needs the fix in the video. Super simple to do it yourself if the dealer want a stupid amount to do it. Sounds like they already charged way too much for what they did on the rails. I replied to your email before I read your comments here.

Just out of curiosity, are you happy with your 28G? I have one on order, should be here this week. I am trying to do as much research as I can, but I can't find any owner reviews on KZbin.

@@2009reezen Yes and no. this is my third trailer and my second toyhauler . I had a 2010 Forrest river shockwave before this 26' and its on road manners were much better then the momentum. With the momentum it is important to make sure you machines are pushed a close to the front kitchen cabinets as possible or it will become very tongue lite . the first time out i didn't have my side by side far enough forward and at 50mph I almost lost the trailer it swayed so bad. (i haul with a 2020 ford f-350). The GD momentums look sexy but all in all I'm finding the build quality to be about on par with other trailers I have owned. I bought the trailer just before covid hit so I still have a regular 120v/propane fridge which is nice. And yes this trailer was one the more expensive side . my dealership sold the 2021's for 10k more then what i bought mine for and they are exactly the same except the rear bunks come with legs and mine were missing. one more thing. these trailers are HEAVY so a good diesel one ton is defiantly needed to haul it. anymore questions let me know .

@@swansong04 thank you for the reply. My tow vehicle is a 3/4 ton Cummins, so hopefully I won’t have any issues there. The weight distribution is concerning, I have heard others comment on there toys causing to much weight on the rear. Can you explain “road manners”? Or is the sway what you were referring to? I have a 30’ jayco today that goes very nice. Never had an issue. I am concerned if this trailer is going to be heavier and not tow well. Have you towed without the side by side? Any difference?

@@2009reezen I have towed the trailer empty and it definitely tows better however not as nice as my old shockwave. for instance I could drive 70mph all day long hauling my old trailer. this trailer just doesn't feel as nice behind the truck and maybe because its just that much heavier, I don't know. GD also pushes the axle gvw of these trailers to the limit. the axles are rated at 12000lbs and I weighed my trailer loaded and it was in the 11000lbs range. on a side note . there are other things i don't like but don't wanna nit pick too much.

Depends on which version you have but the latest version has 4 small gold levers one on each back corner of the lower couches that need to be flipped over to push the upper bed up and lock it in the up position.
