What Else Did I Find on the 2008 Marquis Suspension?

Here is the second part of the 1300 mile road trip. I poorly explain ride height control valves and troubleshoot the driver side and find some alarming issues.
While, I did not end up replacing the valve, I needed to know if there was a serious issue that would prevent travel. I could have replaced the valve but on-site road repairs with bad tools can cause more damage so I opted to limp it home and make adjustments with the leveling system if needed.
Thanks for watching!!

This is rapidly becoming my favorite KZbin channel. James isn’t only an RV expert; he’s an expert communicator. Further, he has that indefinable characteristic that makes him fun to watch and can neither be taught nor learned. We should revere more the “Jameses” of the world. As one with an earned doctorate I think that I can say with some authority that what James does requires at least as much brains and skill as my job and is far more useful.

[@AZExpert]

Thank you very much! That's very nice of you to say

[@SpykersB]

My first lessons on a coaches air suspension, and I’m watching very intensely….surprised myself. Because there is no way in this life time I would actually go and search the internet on this subject to learn more. You could make watching paint dry interesting! Cheers 🍻

What a beautiful coach. Wow, a 600 Cat! I love these old Beaver coaches.

[@Robasteerjock51]

My 08 Beaver Marquis (sister to this coach) has now had all of the ride height control valves replaced as well as the Valid controller board... the solonoids rarely go bad according to the Valid Tech line... good luck, we enjoy following your vids.. you arent afraid to tackle anything, which makes you credible.

Remember that fix well , Went through 3 leveling valves before we found one that worked !

[@AZExpert]

Thanks for watching!

[@badgerpa9]

Thanks for the ride height explanation. When I had to figure out mine on a van a few years ago it seemed like none of the mechanics at the dealership had a clue how it worked and messed it up. Once you spend some time looking at them and finding the spec sheet it really is not hard to hook it up right but you need to follow the instructions. Glad you had a nice trip.

@@AZExpert Diesel defiantly has some advantages..but when I found this model 4 years ago I was smitten and would trade in my 2005 Itasca SUNCRUISER 37B for this rig..now Big Bo is kind of a blow hard but this is a pretty good representation of a 2004 Winnebago Chieftain 39T ---> kzbin.info/www/bejne/rGXIqqxpi91jbbc

[@frankietuned]

The answer is pretty simple and a very easy mistake to make. You actually solved it during you explanation of how the leveling valve works. The leveling valve is installed upside down. The exhaust port should always face down. Simple flip the leveling valve and it should be good to go. On a side note, I'm from Chicago and we stopped at that same exact Chevron on our way to the Petrified Forest by Holbrook.

[@AZExpert]

lol nice

[@solvend]

Road trips are the best. This makes twice you've been through OKC in last few months. Keep on kicking ass!

[@bpnracing1256]

We used to mess with airbag systems delivering decked freightliners. Couple other ways to do it. Best option would be plumb into the good side with the leveller that worked. It would just level both sides the same. 2nd option just put a Schrader valve on a single line coming out of the airbags that were wonky and manually put air in it to get it close.

[@DavidRussell-TheDavidRussell]

Loving your channel as we are about to go full-time RV. Just notices at the 11:14 mark that you were in Morrilton, AR and you drove right by the Morrilton Drive Inn. Best burgers between Little Rock and Ft Smith. Hope you got one.

Agree with you that the line should not be plugged off.... should have been a MAJOR clue to who ever replaced the Ride Height leveling unit that something was not quite right, but in all fairness, it could have been a road repair too..

c'mon back to LR & take a jab at this Class C...2000 Catalina Sport 30ft...I have most parts ready for install, but you obviously know what you are doing...heheh

[@PastorwithoutaPulpit]

The whole time you were under that thing I was on pins and needles. I grew up turning wrenches in my grandfathers garage and almost managed to crush myself once. Now anytime I have to go under a vehicle it's a constant fight to remain under it until the jobs done. It doesn't matter if I know that there's no way for what I'm working on to crush me, that fear is still there...

[@AZExpert]

Its always something I think about.

I own sister coach to this one.. changed all the ride height valves and carry extra..the system is complex..the RH valve is bad

[@AZExpert]

Always issues

[@Kingjamesvii1]

If that is a Barksdale 55521 series cab valve. The two ports together go to the bag or bags. Then the inlet and exhaust ports are on opposite sides. So the spare ports together should have the extra plugged like they did. But from the angles you could get the camera at I couldn’t see the exhaust port.

you are appreciated! good vid

[@petepeterson5337]

My GUESS is that with a correct leveling valve, the old control board will be happy. Different behaviors in a fault condition could be due to different firmware in the microcontroller. I work with embedded software engineers who are very good, but my god can they screw stuff up if there isn't good engineering at the system level.

Are there any Class Cs in the 05' up to say 11' they stand out to you as better quality than most ? Tough question I'm going guess,lol.

[@robertsingletary3498]

I think the lines on the top of the valve are backwards. The pinched off line is fill not exhaust.

[@jams19641996]

Rotate the height control valve. The valve can be used on the left and right side. It was installed wrong.

[@AZExpert]

don't worry I tried that

[@smacdiesel]

[@ianm3343]

You could have plumbed all the airbags to the working leveling valve. Most semi trucks run all the bags on one valve.(also most semi trucks don't have that complicated of an air ride system.)

[@AZExpert]

I was in the middle of a parking lot, so I did what I could.

[@trustme7731]

Pulling into the gas station made it look like it needs shocks.

It needs functioning airbags

[@leewelbanks6366]

This is what you get when you get some so called RV expert/tech trying to repair something they have no idea of what they are doing. That coach is almost the same as my 06 except that I have HWH leveling.

[@bayhi1fatz]

Left side valve on the right side

[@erasmolopez7814]

How about turning the valve around and moving the lever to the other side

[@Nomadiccamping]

Is there a spray on wax you recommend for RV roofs ?

[@jameslowmanjr6141]

WOW. My air leveling valve went bad. My transport look like I was doing a reversed wheelie down the road. Until I got a new one easiest fix is level the airbags off and disconnect the controller arm. But 2 valves for all 4 bags. Something so simple. The RV companies try and improve it which just makes more problems. Sounds to me they tried to put a independent air suspension ride on that. The module that regulates each angle went bad. Then somebody that didn’t know what they were doing just got any air valve leveler and mounted it improperly. But it could just be bad. Because if you pull the lever or push the lever Air should be moving either in or out if it doesn’t replace it. Trying to find parts you could’ve found a truck repair shop they might’ve had an air valve most likely they would’ve but for that system it probably would’ve worked. Been waste of money and time.
