There is no way that working out of a truck is better than a van/box truck.
I don't care what gimmicks you put, sliding draws, cabs and all.
If you can't get into the vehicle and walk around while accessing 4-6' worth of bins, shelves, etc. -- it's going to suck.

Let me be clear: if you're a DirecTV installer that has 3 appointments a day and all you have in the back is a spool of RG6, a ladder, few DTV boxes and a tool pouch -- fine.
But if you're doing custom A/V, than you're going to have 12 different types of cables in 6 different lengths, along with routers, APs, remotes, saws, drills, tools, etc., etc., etc.

Again, running custom integration business out of a truck sucks.
And on top of that you got a FORD?!?
