That would be like trying to make chicken salad out of chicken poop. You would be much better served buying what you need already in place. I wouldn't go near trying to do that.

Man! Where to begin. For starters, I hope you understand that you can't just convert the gasoline V-10 to diesel.

Bottom line is that if you're not happy with the gasoline rig buy a diesel and be done with it.

You cannot convert the engine to diesel. If you try to replace the engine with a diesel you will have weight and space issues to deal with as the engine and transmission will be significantly heavier. Then there is the issue of the fuel shared with the generator so that will need to be dealt with. As was said, buy a different unit with a diesel. It will be cheaper and much easier in the long run.

So are you looking at an engine V10 6.7 in like those that have posted buy a Class A diesel you would need to change out the Gen fuel lines add filter transmission to meet the diesel output and may also need to change out the drive shaft buy a class A diesel even if itís an older

Hmmmm, what if?

What if you got your hands on a crashed dodge eco-diesel?

What if you have access to the ultimate mans workshop?

What if the workshop was next door to the ultimate scrap yard?

Then you'd have a spare V-10 gas engine for your hot rod. Fun!

It has been done but it's a lot of work and probably not cheap. I agree with others just to buy what you are wanting to start with.
I had a mechanic who put a Cummins in his F450 service truck. It was easier to work on then a class A rv but still a lot of work.

Their was a guy that put a Duramax drive train in an older motorhome. I can't remember all the details but he was very happy with the results. There was a thread on the Rv.net forums about the conversion.

With the slower turning diesel, the rear diff. would likely need to be re-geared.

WELCOME to the forums...

I would have guessed if you're actually traveling (driving) for 4 months out of the year, the drive ability and ride would have been more of a factor than power from a gasoline vs diesel, and you would probably move toward a DP for that reason.

With that said. Yes, Anything is possible, but I don't believe it would be worth the expense of converting a gasoline (and possibly transmission) to a diesel.. Engine and transmission, and their control modules also need to be factored in, along with the mechanical, motor mounts, linkage, etc, etc, etc.. AND - When you're finished, you would have a "one-of"

If power is your concern, The only real difference between gasoline and diesel in the turbo charger.. There are aftermarket add-on turbo chargers and super chargers available for gasoline engines. This approach might be less expensive and an easier conversion than a full diesel / transmission swap.

I'm running the older low power version (275/305 hp) of the V10, and haven't run into any problems as far as power. While I'm making an 11,000 ft climb up I-70 at 25 mph with the four way flashers blinking, I watch the DPs zoom by me at what looks like 70 mph. Thats OK, I make it to the top, I just do it a lot slower..

Theres a big reason we didn't opt for a diesel powered coach. Cost and ongoing costs. As for power..... There is no lack of power in the newer V10's. I pull DP's up grades with a 3000 lbs trailer (with a SXS and BMW GS)...... But hey, we live in the US and freedom is the name of the game.....

OK, if you want a Thor Outlaw, and diesel, buy one of these:

2014 Thor Super-C

2015 Thor Diesel

2010 Damon Toy Hauler (with Cummins!) FrED

There are more out there, but I'll let you have the fun of Googlin' them up!

I'm also curious as how you've decided that the V-10 gas engine isn't suitable for your purpose. Have you driven one or spoken to those who have used one for the same application you've got in mind?

I thought the Outlaw came in a Fred diesel at some stage.
