Stress cracks from square corners? This may be an issue for their builds, but this is not an issue for all.
In a previous discussion, you mentioned excessive cost of Bill's products? What is a fair cost in your mind? Just curious.
Stress risers at sharp corners is an issue for many sheet materials - even aluminum in some applications like aircraft (typically much thinner). You familiar with the tombstone engineering of the
de Havilland DH.106 Comet?
To be clear - I don't think Globe Trekker products are unreasonably priced considering todays market pricing. But in the interest of leveraging as much value as possible from the military surplus channels and assuming you can live within the constraints of the size and aesthetic qualities of the 1079 or 1087 - just like the truck is now 1/10th the price the military paid - so is the enclosure. It's a better value if it serves your purposes and even Bill isn't going to argue that point I'm sure. Supply vs. demand and of course if you need/want something of a different size then the surplus choices are limiting unless you want to modify them (has been done).
Aluminum is a nice material and they all have their pluses and minuses. One issue is repairing it. You may not care, but how would one fix a nasty thick tree deep scratch? Bondo maybe? Not being disrespectful, just curious.
Oh that's easy. Either spray foam and bondo, or a riveted patch panel. Very easy either way. I keep my truck painted with flat CARC style paint so a rattle can for touch ups and rust spots is the order of the day. Just like when I was a PVT - head out to the motor pool with sand paper and a case of paint and make the trucks look good for inspection!
The outer skin is pretty thick - branches and other wooden obstacles usually just get OWNED by the box. Broken off and tossed aside, etc. I've never seen a mil truck with a puncture through the van skin. Would probably require hitting something more substantial than some branches. Take a look at my cross-section pics from window install. The only damage on my box was on the rear door where the grunts damaged the panel from cutting a lock off the door. Dented and a couple cuts from an angle grinder wheel. Bondo and a random orbit sander running off the truck's air sorted that out in less than an hour. Rattle can CARC and it never happened.
And yeah the appearance is subjective but there's lots of options out there besides Army trucks if you prefer the iPhone aesthetic and everything covered in cheap plastic.
