Nice build! It wasn't common for a five ton to be off highway one unless it was close to home. But alas, most of highway one was crushed gravel at best. Yes the were stretches down south that were black topped, but up north that usually meant you were within four miles of a big base. Most trucks lost their tarp within a couple weeks to make a bunker roof water proof. The cab tarp was also lost very soon as it was restrictive to getting out of the cab during an ambush. In the end, a truck in country six months lost the wood slats, but might retain the seats. A spare tire in the back usually was lost at the first stop! Some units chained and locked them up back there.
We kept ours in the normally stored position, or had none at all. A flat was usually in the rear anyway. One thing a lot of builders fail to notice was the winch. It was near impossible to get all that cable back on the the drum!! So we wrapped it around the bumper. A truck in the rear seldom used the winch, so you did well. The cable is stainless steel and coated with grease ( brown, red, or green). Of course it picks up a lot of dust.
I plan on doing a well used M54 and a couple road hard and put up wet M35's.
