How to Build a Quiet Box for Your RV Generator! DIY

We purchased an inverter generator for boondocking with our Travel Trailer. It’s a quiet generator but wanted to see if we could make it quieter as well as protect it from the outside elements while camping. We wanted to share how we built it and how it works. If you are considering a quiet box for your generator, we hope this video helps!

I like running my Twin Cylinder Harley generator with straight pipe. People love it. You'll notice they immediately turn to look at your awesome generator.

[@OutsidebySide]

@Oldworkinman Lol! Funny! Thanks for watching. 🤩

[@loganjvmes]

I recommend using acoustic isolation board or foam too! I’m a certified audio engineer and there really is a science behind sound isolation. It’s amazing. Great vid 👍

[@OutsidebySide]

@Getleaux Thank you for the suggestion & thanks for watching our video! 🤩

For my 4K watt Champ I built a box 8 years back. 3 foot square 3/4 ply / 10” fan / hinged lid for fuel / side cutout for access to start switch and receptacles / 4” casters (2 swivel 2 fixed) Fire/soundproof insulation / One open end obviously to take genny out for maintenance. Dropped 19 decibels - happy and no complaints!

[@OutsidebySide]

@FrogLobster That sounds awesome! So happy for you & thank you for sharing. We always like to hear ideas! Thanks for watching our video & we would appreciate your support by subscribing to our channel! 🤩

[@froglobster]

@@OutsidebySide You got it! New sub as of now! Thanks for liking my box plan!

[@OutsidebySide]

@@froglobster Thank you so much and thank you again for sharing your ideas! 💡

[@Osiel1987]

Thanks for your help and recommendations Have fun and be safe guys every video is very helpfully Thanks

[@OutsidebySide]

@Lord Osiel We are so happy to hear our videos have been helpful. Thanks for watching & happy camping! 🤩

[@nt3063]

Awesome thanks for the idea. I’m gonna do the same to my generator.

[@OutsidebySide]

@nt3063 We’d definitely like to hear how it turns out. Thanks for watching! 🤩

Hi there. Getting ready to embark on my skoolie journey. I have a wonderful generator & my next project is to build a box to prevent theft and damage. I am in a little bit of overthinking territory - how would i fire proof this box in a cost effective way? I feel nervous about having an engine in an enclosed wooden space. I have plywood available, so thats what i was going to use.

[@OutsidebySide]

@jordandebbrecht3276 Thanks for reaching out! Our recommendation would be to line it with Densglass which is fire resistant and sound deadening. They sell this at Home Depot. Hope this helps! Wishing you the best. Thanks for watching. :)

[@mike9672]

This is a great idea!

[@OutsidebySide]

@mike9672 Thanks for watching! 😃

[@OPSteel97]

Love you guys! I am going to build this quiet box mostly for rain protection (Seattle area).

[@OutsidebySide]

@Chris Thank you! We appreciate your feedback & for supporting our channel! Please let us know how it turns out! 🤩

The Box need to be bigger and full enclosed, with air intake & exhaust with baffle. You need to add Rockwool insulation all around to absorb to sound. Then you need to add something like an attic exhaust fan on the top of the box to suck out all that hot air and fumes, then add air intakes all around the bottom of the box. I used a large plastic storage shed with my 6500watt generator and it worked perfectly! all you hear is a low humming. cool air is being sucked in while hot air and fumes air being pushed out.

[@OutsidebySide]

@iiinsaiii Thank you for your recommendations! We appreciate your feedback! This box has worked perfectly for us and so happy to hear you have found a solution! Thanks for watching! 🤩

[@ashtonallen6434]

I love this design. The other videos of boxes I've seen with the vents and fans etc., just seem over the top. What is the longest period you would say you have run the generator in the box? Did you notice any heat or exhaust build up?

[@OutsidebySide]

@ashtonallen6434 Thank you! We really like the simplicity of this box. It does the job. We have run the generator consistently overnight with no problems. Thanks for watching! 😀

[@joelcawthon1365]

how do you plug stuff in with the box on it ?

[@OutsidebySide]

@joelcawthon1365 We allowed a space at the bottom which you can see at the 8:30 mark. Thanks for watching! 🤩

[@jwlindem1]

You look like an expert 😜

[@OutsidebySide]

@John Lindem Thank you for the compliment but we are definitely not experts! 😂 Just many years of learning as we go! 😭 Thank you for watching our video & hope you have subscribed to our channel! 😄

[@terp6097]

Thanks for sharing that, some helpful tips for what I want to build

[@OutsidebySide]

Great video! I noticed your Big Bend hat. This park is the reason we are planning to create a box. We can't use the generator in the park but there a plenty of remote camping sites just outside the park that allows it.

[@OutsidebySide]

@Jerome Edwards Thank you for watching the video and your kind feedback! We LOVE Big Bend and plan on going back soon which is definitely one of the reasons we made the Quiet Box as well! We are definitely on the same page! If you haven’t already, please subscribe to our channel for more informational videos! If you make one, please let us know how it turned out! 🤩

[@hurleystowing]

How long have you used it with the cover on it? I’m in central Florida and it’s hot, mine needs wide open space or it will trip the breaker on the WEN….. just running a 21ft camper 13500btu ac on like 70ish degrees, it’s a shaded campground so not direct sunlight. I’ve run it with a couple of pieces of tinted plexiglass laying on it like a TP with carpet over top to blend in because “quiet time is 10pm”

[@OutsidebySide]

@HorseHead Mike We have run the WEN all night with the cover on it on several occasions with no issues. It has been in cooler climates and we haven’t used it in warmer climates much. If you are having issues, you can install a soft start on your RV A/C which could help. Thank you for watching our video & we would appreciate your support by subscribing to our channel! 🤩

[@joewoodchuck3824]

Install a fan to either push air into or out of the box. You'll need an intake hole and an exhaust hole either way of course.

[@donc6545]

Awesome project. Great team work.

[@OutsidebySide]

@Don C Thank you for watching our video and for the encouraging comment! We hope you subscribe to our channel! 🤩

[@ronreade3297]

Good video. I hope you know the nail gun has to be depressed against the wood to wood to operate. Would carpet pad work for sound insulation?

[@OutsidebySide]

@Ron Reade Yes, we use the nail gun often & it stopped working. Good observation! Carpet pad would definitely help with sound insulation! We appreciate you taking time to comment & thank you for watching our video! 🤩

[@RaulHernandez-ib2rk]

I love it

[@OutsidebySide]

@Raul Hernandez Thank you for watching our video & taking time to comment! We would definitely appreciate your support by subscribing to our channel! 🤩

[@jamman1027]

Use medium density fiber wood. Will hold the spl better than ply.

[@OutsidebySide]

@jamman1027 Thanks for the tip & for watching our video! 🤩

[@davidlewis9068]

Too bad you did not have a piece of clear lexan for the front piece.

[@OutsidebySide]

@davidlewis9068 We had clear Lexan, but used acrylic instead because the lexan tends to cloud & yellow in the heat a UV rays. Thanks for watching! 🤩

[@waynerlg]

Why do you need to make it so tight? Give it a little breathing room

[@OutsidebySide]

waynerig It has worked for us so far! Thanks for watching! 🤩

[@shawncell1247]

lol

[@OutsidebySide]

@shawn cell thanks for watching! 🤩

[@ronnjerremy5796]

😂😂😂😂

[@headon62]

👉🏼 Your nail gun was working and I don’t think you knew it. 🤦‍♂️ The tip where the nail comes out has to be pressed against something 👈🏼 Your generator was already quiet enough. One shock thing after another like having to slide styrofoam in the box that’s not attached👈🏼 From 1 out of 10 I give this video a 3 🥴 Have a good day 😊

[@OutsidebySide]

@Animal/Rights A.R.A The nail gun was not working but thank you for your input. There were many attempts to use it that was not included in the video. We actually had to replace the hose.
