That's one good looking truck! The .50 mounts are a work in progress. Since I open the truck bed for people, mostly kids, I set mine to maximize internal space. As time and money allow, I'll continue modifying them till I get them just right. As for the rear mount, I plan on buying one more resin gun and making it a double mount. We'll be having an event on the 16th from 10:00 to 2:00 over at the Cheyenne VAMC. You're welcome to bring the truck!
