Because it is interesting to know how long it takes a guy working by himself, who doesn't have a big workshop with lots of fancy tools, to build/convert something like that.
As regards aesthetics, we all have opinions about what we like (mine is "stock military"), but in the end the only person who has to be happy with Militarytrucks' work is the customer who ordered it. If he wanted those huge tires and an M105 bed (which he did), then that's what he gets.
This truck is not my cup of tea, but I did find it interesting to stop in regularly and watch it get built from a "gee whiz" point of view. It was definitely not a simple case of whack off an axle, jack it up, and put on big tires.
Cheers
