I will make sure that the carbon monoxide detector is in working condition. If we have co issues in the camper, I will use the venturi, or some other solution.

Carbon monoxide is produced by badly adjusted combustion.
Engines release lot of different poisonous gases.
About 20 years ago I bought 12v plug in detector who had several sensors, including combustion gases. When I had to way to test it, it went off 1 time when on classA I had "doghouse" cover open and diesel engine running.
Have not seen such detector since, so is CO detector the only protection we can get in 21 Century?

I made some more progress on Project BIG today.

I decided that I don't need the outlets on the control panel, since the generator will be hard wired to the campers electrical system. So I pared it down to the essentials, and cut down the control panel. I was planning to mount it in the generator cabinet, and use the wireless remote to operate the generator. But the thought has occured to me of extending the wires and mounting this inside the living space...

I have quite a pile of left over parts:


[image]


The dimensions of the generator, all stripped down are 19" x 15" x 12.5" tall. It weighs 55 lbs. THe plate that came with the camper weighs 23 lbs. By the time I get done with this, I expect to add 65 lbs to the camper.

There are 2 fans, one for the engine, and one for the generator. They both exit the same side, and the muffler is located within the shroud for the engine cooling air. So I got some 12 x 2.25 rectangular duct and made it into a shroud to route all the cooling air out the bottom of the mounting plate and into the atmosphere.

THe spark arrestor was attached to a flange at the exit of the muffler with a couple of little metric screws. Since I need to attach the exhaust pipe to it, I drilled and tapped the flange out to 1/4-20.

Then a made up an exhaust pipe flange out of some 5/16" steel plate, and welded a 3/4" pipe nipple to it, at just the right length to reach thru the shroud.

I ground the mounting surface flat and smooth for a good seal.

I used some high temp form-a-gasket and attached it to the muffler.

Then I installed the outer cover for the shroud, and threaded an elbow onto it.
After the generator is in the camper, I will thread a pipe into the elbow, cut to the proper length, then another elbow to a tailpipe out the back.

Awesome build!
Curious on the sheet metal bits, where edges touch other surfaces, folds etc. Will vibration cause noise?
On our built-in, though loud outside not too bad inside, even though on isolators ,its the vibration that's transferred thru out camper that makes it seem loud..Id be tempted to add rubber between mount plate and camper.
But not to distract-enjoying your efforts. Like the remote mounting of panel

That's a very good point, so I'm going to make sure the sheet metal shroud dosen't touch anything. I think I'll seal it to the base with rubber roofing membrane that won't transmit vibration.

To insulate the cabinet, acoustic ceiling tile seemed like a good idea. So I picked up some glass and some perlite panels. THe first thing was to test them for fire resistance and they passed by not catching fire.

Then I glued the glass panels to the 3 sides and the top of the cabinet, then added a layer of perlite to the back and top. The back is adjacent to the basement, the top us directly under the living room floor, the front is an exterior wall and the back is adjacent to the battery compartment. So the top and back are most critical. The front and back are tight for space, so I'll just use the one layer of glass. I'll put some asbestos between the exhaust pipe and the fiberglass for insurance. I'm also going to add a few screws/washers to each panel just in case the glue doesn't hold up.

I have often thought why camper manufacturers do not at least offer this type of gen set as an option.



It is all about liability. The other mfg's like Honda don't make a built in generator. As far as I know Onan is the only one selling a built in generator. People don't realize how much the cost of product liability insurance is.
