Interesting project. When I was active in the Michigan Knights FMCA club there was always a few FMC motorhomes at the GLASS rally's. Enjoyed spending time talking MH's. One member from western MI. was always talking about installing a diesel in his like others had. I am sure Barney is following your project.

Yes, Barney has been following it. While I live in OR, I expect to see Barney next June at a rally in Carthage, MO.

I have subsequently checked my speedometer against my GPS and they actually match so all of my dash and DIC info is correct within the limits of GM's accuracy. That is convenient as no translations of data are needed. For the first 250 miles I have averaged 12.9 mpg as compared to the 7.0 I got with the 440. That will increase with highway miles and decrease when I hook my toad up.

Steve, I doubt you will see much difference with the toad as the MH is the most drag you will encounter, unless you get into some very steep climbs. 12.9 is very impressive mileage for something that weight and frontal area.

You were correct in that on Wednesday when I went home to Oregon with my newly running coach with the Brat in tow, for the 583 mile trip up I-5 I got 13.1 mpg. That was from the DIC and by careful filling of the tank at both ends of the trip.

And, yes, it is more than what I was expecting considering that the trip involved two passes of 3000+- and the Siskiyou Pass at 4300 ft with 7 mile 6% grades on both sides. I need to increase the heat rejection rate for the grades, but it is a very fun and enjoyable coach to drive. It can pull 6% grades at over 60 mph!

I've always admired people who not only can they come up with good ideas/projects, but can also keep working on them until finished. I can imagine the feeling of accomplishment when you first drove it. It's pretty amazing really. I hope you get to see lots of drive time in this great motorhome. Thanks for all the photos and videos. I betcha most of us wish we could've been there. Congratulations

I thank all of you for your kind comments. It felt great to actually drive it while knowing it was something that I created. And as a bonus, it performed just as I had imagined that it would.

My Son, who is visiting us right now, has that same engine/transmission combo in his 2500 Chevy pick-up. He uses it to tow a 5th wheel. Modifications done to his combo include a 4" exhaust, a cold air intake, and a programmable monitor that allows him to make changes to the engine computer "on the fly" to adjust for various conditions. It is a great combo for your coach. Congrats!
