I made it home last night about 9:30; the trip was uneventful and the bus ran out good. I stopped at my brothers place, about 100 miles into the trip, and we changed all three fuel filters. It had not been done for years and I'm sure and it needed it. We also replaced the primer pump on the fuel pump as it wasn't working. My brother is a diesel mechanic so this was all just routine stuff for him, besides, he has a nice shop on his farm.
The insulation under the bus is around 4" thick. However, I doubt the insulation in the wheel wells is more than 2". The cost to have someone else do it was $600.00. I couldn't buy the materials, myself, to do it for less than that price. This spray foam has a coating on it like the spray foam roof materials you see. I suppose you could spend the extra money to give it more protection but I don't forsee driving it enough to justify the extra protection.
As far as MPG; I can only speculate as to that because I've not filled up yet again. I've got a 1/4 tank left after the trip but have no solid numbers as to the tank size yet. I'm assuming it's around the 10 mpg ranger or so; I'll know for sure once I fill on the way back to work in a couple weeks.

If you don't mind- how much did it cost to get the under side spray foamed and how thick?
In my planning/thinking the foam underneath would need some kind of protection from road wear. I started to look into roll-on or spray-on bed liners (diy of course) for this purpose. I guess we'll all find out when you get back- safely of course.
