Dumped The Onan

I am certain most everyone knows how expensive that Onan Generator is to fix and/or Replace.

When I started working on my old RV The Onan didn't work and appeared as though someone who knew nothing about it tried to fix it. I pulled it out and spent a couple Hundred trying to get it going to no avail.

Well I later bought a Construction generator from Menards and put on a Rack That Hung off the Rear Hitch. That worked ok but was always trying to think of a way to install it where the Onan was.

I tried to use Ratcheting straps. It only had 4 inches of ground clearance. So I quickly figured that wouldn't work. Plus i didn't trust the straps So I accepted using it off the rear bumper.

However I am Stubborn and wouldn't Let it go. So I came up with the Ideal that if I cut the Frame on the Generator, Removed the Tank I could Mount it on a 2X6 Plank and Bolt it into the Onan Position.

Then I Bought a Smaller Metal Gas Tank And mounted it in the Rear compartment.

Thought I would share with everyone and post some pictures.

Nice! Are you able to run it through the control panel inside the rig?

I’m sorry to rain on your parade, but:

Gasoline in an enclosed compartment?

An open frame generator in a space with restricted ventilation? I expect it’s your intention to leave the doors open in operation.

I know first hand a guy who had a similar installation in his off grid cabin. Past tense because wind blew the door shut and it caught fire and burned the whole place down.

Be careful.

Onan's also have spark arrestor mufflers the meet the fire rating. Do not start grass fires. No sparks.

Thank you for the response............... Hey Look I understand this isn't for everyone. But perhaps someone may get something out of it.

It is open on the bottom and all 3 of 4 sides. only the Top is enclosed. I may prop the door open but not sure and not really worried about it.

If i carry gasoline in the trunk of my car isn't that the same thing as what i did here?

I do intend on Making an exhaust pipe to direct the exhaust out the side.

Thank you for the response

Water is really bad for generators, you need something to protect it from what is going to pour into that compartment from the duals.

I did the same thing but with propane. Some said it would over heat.
I don't know how to steer you to my post but it is titled "25 yr. old Onan vs. New Portable".

Like Red Green says "If they don't find ya handsome, hope they find ya handy"

Looks like it should work.

I'm just wondering why you didn't just use the fuel line for the old genset?

You wouldn't have to worry about topping up that little tank any more.

Happy Glamping.

Thinking about it. The Onan had a pump on it.

I would need to come up with a pump system of some sort. The line going into this generator is no more than windshield washer fluid size. Very small. The onan line is like 3/8 Fuel line.

Honestly just haven't come up with a solid idea. That tank is steel and Holds 2 gallons probably good for 3 hours or so.

Maybe i could put a small electric pump on that old onan line and run a hose to this tank. Control it with a switch. Then I wouldn't have to take a gas can..

Hmmmmmmmmmmmmmmm.. To be Continued............

Facet makes small electric pumps, get one with only a couple of pounds of pressure and it shouldn't be too much for the needle valve. You can then get the correct hose fittings for the fuel lines.

So why not either run the generator off the fuel tank line the Onan ran off of, or mount a small pickup tank in the frame rails and put a fuel neck next to the factory one?

I converted my Coach from gas to diesel and kept the Onan gas generator. For now!
I added a new 13 galllon small pickup gas tank under my coach and ran a long fill pipe to the rear of the Coach and put it's gas fill cap next to the Original fill neck that is now a diesel filler.

I fill both tanks without having to relocate the Coach at the fuel pump this way.

And BTY, I helped a Bus Nut last year install an under floor generator using 500 lb slide out brackets.
We just cut the side of the bus, under the floor and made a door and hinged it for generator access. Then added door latches to the new made door.

The generator, tank and all are hanging out in the air. Under the bus. The only thing we did was add a longer exhaust tube to run it our away from the Bus. The owner just slides the generator out to fill the tank.

Open frame generator = too much noise. Not the way to win friends at the campground, even Boondocking.
