I see a new Paris Dakar support truck in the making
OEM is a whopping 58 MPH. The final drive is just shy of 8:1, but there is an alternate R&P which fits and brings it down to a sensible 6.3:1. Thankfully, my rig already has these in the pumpkins. I've been to the low 70's in it, and that is plenty fast enough. The whole point is to take in the scenery. RPM at 60 becomes much more tolerable, and there is a minor mileage bump as well.Chris - what is the top speed of the vehicle? Must be geared very low as an Army truck?
XPS foam sheet. Cutting out the various needed shapes and assembling like a puzzle. They will be sandwiched between the outer skin, structural members, and inner wall (1/2" ply). I will tape up over all the seams to seal it all up as well as possible.What are you going to use for insulation?
