Does anyone know the fuel economy of the new Thor Super C? The Super C with the 6.7L Diesel engine by Ford. Since Diesel cost est 14% more than Gas, a person would need to increase the fuel economy by at least that much to break even on fuel. Lets not forget the better torque.

You will likely ever recoup your investment in fuel savings. Increasingly, fleets are turning back to gas motors. Ford says the F650 V10 uses about 10% more fuel than the 6.7L Cummins. I think the DEF-equipped Cummins are very compatible in fuel consumption to the Ford 6.7L.Also keep in mind the diesel in the cab/chassis makes less power than the pickups.

My E450 has 305 hp and torque is 420.The new Thor Super C puts out 300 hp but torque is 660. I can tell you which one I'd rather have under the hood of my E450 - and it is NOT the V10. Don't know why they shy away from putting the 363 hp version in the C. It can use it IMO. Don't know if we will ever get another MH but if we do the Thor Super C will certainly be on the list to consider. Unfortunately Thor may not be smart enough to get our biz. When looking at the Thor site I used the dealer locater feature. We live just across the river from Detroit. The nearest dealer in Canada handling the Super C is in Quebec. I let them know in no uncertain terms that we'd never consider being that stupid. The irony is that we have an RV dealer less than a mile away. It handles Jayco and Coachmen Class C's. It also handles the Thor ACE Class A. One would think that this dealer could obtain a Super C - but Thor hasn't figured out how to market its products yet. :(

Thanks for a quick response. I have some experience with Gas v Diesel. I purchased a 2010 40ft Fuzion-toy hauler when it was 6 months old, at a substantial discount, because the owner hated towing it. A huge RV, with a weight of est 14K lbs. The owner towed it with a gas powered Chevy Dually and could not get above 50 MPH and I did not bother to ask his fuel economy. His truck was the delivery vehicle to bring it to me, just before I had a 5th wheel hitch installed in my truck. His truck would not back the RV up the slight incline of my drive, just-no power. I have a 2011 F450 6.7L and THAT RV pulls fine with about 10 MPG. IT IS BIG AND HEAVY - BUT BEAUTIFUL, IN AND OUT! :) Last month, coming back from Galveston with this RV in tow, I looked down at the spedo and discovered I was doing in excess of 70 mph, and promptly slowed down. I also move a D5 Dozer, 19K lbs, and a Track Hoe, 14K lbs. My Ford Diesel runs GREAT. NOW - I also got a great deal (estate sale) on a 27ft Ford-Freelander motorhome, with a Gas-V10. Poor economy and not much power. This is my 2nd V10 - previously I had a 2004 - 30 ft, with est 8 MPG. I have been in the mountains with both motorhomes, a small trailer and fuel economy is 8 MPG and as I mentioned, poor power. MY GOAL-I STILL WANT TO FIND OUT WHAT THE FUEL ECONOMY IS ON THE THOR=Super C. Due to the difference in cost of Gas v Diesel, I desire to NOT spend MORE on fuel than I am now, even though Diesel cost more. Also NOTE, I have a 6.7L in my 2011 F450 and love it! Powerful, quiet and will pull anything I have the balls (trailer balls-LOL) to pull. Generally- IF?...the Super C gets only 20% better economy-then I am in- due to the increased torque, increased towing limit, and/or NEW, etc. Remembering that a 20% increase over the current 8.5 MPG, is only 1.7 improvement, justifying the higher fuel cost and getting a NEW motorhome. :)

I am mainly looking at the difference in torque of a Diesel v Gas rig. I have a 2011 Ford F450 pick-up truck with the 6.7L Dually, long bed and King Ranch Edition (this is Texas guys!) I love that truck, strong, quiet, and pulls anything I own. Also, it is garage kept, YES-I do have a garage large enough to park it, 'cause I BUILT THE HOUSE. :) My truck currently is 2 years old with 22K miles and zero problems. MY pervious 2006 F350 6L had less power, was noisy and I was glad to trade it at 5 years old with 69K miles since the head gasket was replaced when the truck was 2yrs old. Thanks for ALL the GREAT comments and info. Jer in Texas

Diesel pricing will vary widely with season and location, currently in the Midwest gas and diesel are priced the same and in some areas l is 10% cheaper than gas.

In the east diesel competes with home heating oil so in winter the price will go up and summer down.

Just finished a 2200 mile trip and diesel vs gas pricing was -5% to +16% .

That super C has merit, I tried to find one to test drive.............big question is how noisy is it in the passenger area. FRED (front engine diesels) are known for noise and other class A front diesels did not sell well, and many are traded early. Many manufactures stopped making "FREDs." A smaller class A chassis diesels are more common like the Palazzo.
Nexus is an other super C that I thought was priced well, that has an International chassis.
Dealers seem to be afraid to order super C for inventory..............
