Why not convert the ONAN to a portable?

Thhat Champion you cited sounds like it might be a contractor's model (That wattage usually is) ear plugs are NOT optional. they are necessary with Contractor's models.

Build a box to enclose the ONAN and load it in your truck to carry. you may wish to convert it to gasoline though.. Propane it sucks lots of.
No the champion is a inverter enclosed generator, it replaces the 3100 model with 300 more running watts and you can get it with remote start. I do have a champion 3500 open frame in case of power failure at the house, still new in the box. I need the truck bed open for a couple of maxi-scooters.

Building a rack on the tongue would be far simpler and if you bolt it in place with a cover, it won't be an obvious choice for theft. Plus you get to keep the under bed storage.

Under the bed, exhaust and heat are probably the bigger issues as opposed to noise. The portable generators are not designed to be run in small enclosed spaces.

The Onan is NOT a portable generator. Under bed would be no different then any other built in installation. Onan has a built in fan that sucks in cooling air and blows hot air to the under side of the RV. The exhaust runs through a tailpipe past the exterior of the RV. To install in the storage compartment you would need a sheet metal cabnet that has a lip to the outside of the RV. You would have to cut a rectangular hole in the floor for the cooling with the tailpipe running through the same opening. The generator is in it's own enclosure and designed for this type of installation. This is no different then any other built in generator installation. The Onan 2500 microlite is used extensively in truck campers and class c's. The Onan 2800 is the same generator but the gasoline version instead of propane.

I hope this clarification helps for those that don't understand.

In addition for what it's worth ... Onan's meeting of National Park noise requirements apply when their models are "naked" in only their own enclosures. Built-in Onan generators can be much quieter than their naked noise specs when installed within the various RV generator compartments.

Thanks Pnichols for pointing that out. If I install it will also go in a sheet metal cabnet covered with Dynamat noise reduction material then have the wood bed frame and mattress for additional noise reduction. I could put in additional sound insulation on the bottom and sides of the bed. You will always have a little vibration which doesn't bother me. The motor and generator are on rubber mounts inside the case.

I understood...I was referring to the champion on the tongue and the onan inside.

Yes, you can do it under the bed but its a little more than just shove it in a compartment and hope for the best.

That's why I posted a detailed explanation of how to do a generator compartment. Your correct in you can't just put it under the bed. Installation of the Onan would be a little more labor-intensive.
