Howdy from Houston Texas. I just found this skoolie forum and I'm happy to share any info that might help. I'm a life long mechanic from child to adult. It seems childhood dreams become adult projects in my world. I've purchased a couple ThomasBuilt busses, 18ft. short bus, and a 24ft. shorty, full size, to couple up to previous projects. My previous projects were then and still are, 5 ton military surplus 6x6's. So I've married the trucks to the busses, and created two awesome on road/off road skoolies. It's been a bunch of fun. They certainly have attracted lots of attention from friends and onlooker's. Being that I've gained a bit of knowledge from these trucks and engines, I'm willing to pass it on where possible. I have a 7.3 powerstroke, DT444e, 8.3 Cummins, and a 14 Liter NHC250 Cummins. I look forward to meeting you folks that share the same kind dreams.
