I recently purchased the Champion 3500/4000 genset. My Onan was shot and it was on sale at Blain's Farm and Fleet for $250. I decided to mount it in the enclosure where the Onan was. This is a 1996 Eldorado Class C.
Main motivation was so that I could run it while going down the road to run the AC. I've seen a few people mention it, but haven't seen a detailed post on it, so here goes.
First of all, the generator was too tall to fit in the same space as the Onan. Besides, I wanted to run it off of the RV's fuel tank. So I removed the fuel tank and cut off the top of the frame. The fuel tank vent line is routed to the clean side of the air filter, so I plugged that with a bolt and RTV.
I then mounted an Onan replacement fuel pump on the front of the unit, a Holley fuel pressure regulator on the side, and put a fuel filter inline.
I mounted an electrical box with a solenoid to the back side of the control panel.
Here is the solenoid that I used:
Supco 90341
You can also see in the above picture a stud for 12V power and the inline fuses for the fuel pump and the fan.
I wired it with a momentary push button to the normally closed terminal that was connected to the fuel pump. That way, I can prime the carburetor before I start it.
I wired the solenoid so that it will be activated when the generator is producing 120V. When activated it sends 12V to the fuel pump and fan.
I didn't get a good shot of the fan, but I mounted it below the unit to the RV frame. You can see it in the exhaust picture below.
I wired the RV electrical directly to the RV plug.
I added a bracket and rod to extend the choke handle.
I mounted the unit in the enclosure. I used a 1 1/4" exhaust pipe with a 90 degree bend to route the exhaust out of the closure. I had to bend the end of the pipe in order to make it narrow enough to fit between the screw heads. I fabricated a plate to mount it to the existing screws. 1" or smaller pipe would fit better, but had a hard time finding exhaust tube that size. I also used an exhaust hanger to support the pipe.
Finished install:
Overall, I am pleased. I would have done the exhaust differently, and ran into a few glitches along the way, but overall was fairly straightforward.
