Replaced my Generator ... Help

The Champion generator is more than a cut above a contractor's generator. It has a good electrical output and a very good engine, and is fairly quite. Cooling and exhaust will be your main concerns whether moving or parked. Adding some sheet metal to the top corners as coping will help with both issues.
Since this is a band bus, I would add at least 2 battery powered CO/smoke detectors to the inside for protection. Most will be sleeping, except the driver, anyway, you don't need any surprises.
Good luck.

Yes you did then you laugh at the responses you get. I for one will not offer you any more comments on any of your posts.

Yes I did lol.

LOL what a bunch of skeptics. The Rv is used for a band bus and 95% of the time is on shore power. We only want to use it occasionally driving down the road. So Yes I am going to put louvers in the door and mount a helping fan beneath the unit to assist with the internal fan that blows down thru the open bottom and draw fresh air in. I will send a bunch of pictures when I am done. I am determined you don't need to spend 4500 for a generator because you have an RV. PS: of course the exhaust will be extended beyond the chassis.

You did ask just people's responses

here is a short video of the proof of concept

I bought a Champion 4k. The Onan was the Micro 4k.

To make the genny fit I first removed the gas tank. And installed a low volume electric fuel pump. Then I wired the genny into the coach. (my shore power connects in plug in a different bay)

I added two vents to the door a 12x12 and a 8x8. Then I placed 'Temporary" a box fan to the open bottom sucking out. So far after 1 hour my compartment temp has risen 3 degrees above the outside temperature

I don't know how to post photos...

Curious. What is the brNd and output of the replacement vs the output of the original?

Depending on how you want to use the generator why hook it up permanently at all? It was made to be portable so why not just get a cord that goes between it and the inlet to the RV, use the compartment as transport only and when you camp, put the generator outside and run it there as it was meant to be. Of course these puppies are noisy and you're not going to make many friends but they are not designed to work in an RV compartment, or any enclosed space at all. By the time you get done playing your going to have a cheap, fail-prone generator that you spent three times as much money trying to get to do something it wasn't designed to do. I too had this idea but after much research (Among other things I'm an engineer.)shelved it in favor of a rebuild of my old one. Balanced the crank, new pistons, rods and rings, honed it. Purrs like a kitten and does the job as designed. Just remember, sometimes you eat the bear and sometimes the bear eats you. This is one of those times.

I too would love to get rid of Onan in my RV life. I'd love to see someone get this successfully done, so I wish you all the luck and look forward to seeing some updates and pictures! I recently replaced my Onan with a new one. I maintained my old Onan 7000 perfectly and yet it was nothing but trouble every year. My Honda generator was totally neglected, and yet it has NEVER been in the shop for repairs! I was thinking the solution could be to remove the Onan from the bin, install a hitch carrier with an enclosure for a Honda with remote start. On the enclosure, make a small door that opens for the exhaust and power 2 12 volt fans on the enclosure (one sucking air in, one blowing air out). Could power the 2 fans from the 12 volt source on the Honda generator. The power output could be made so that when you unplug from shore power, you could plug into another outlet that is supplied by the Honda on the generator but close to the shore cord area inside the bin. The idea that the Honda would not pull fuel from the main tank is not that big of a deal, because the Honda fuel tank itself might have enough capacity to run many hours before needing to be refueled. Would also be easier to treat ethanol enriched fuel because you would only be treating the generator fuel, not the entire motorhome tank. A Honda on the hitch is not the perfect solution, but it might be a reasonable one when you are simply tired of pouring more and more money into the Onan, and wanting the reliability that the Honda provides. Reliability over convenience with the Onan might tip the scale for me next time.
