I've got a 2011 1/2 ton Chevy 4x4 extend cab with 8' bed and an A.R.E. aluminum contractor cap. I feel it is a very good vehicle for my needs. I don't usually pull anything stupid heavy so a 3/4 ton or 1 ton is unnecessary, and the 1/2 ton gets way better gas mileage. Having a 4x4 was a must when I have to pull in a field or construction site to put up a 4x8 post and panel and it's muddy/snowy. The cap allows me a dry area for interior
signs, or I can lock everything to keep my tools, etc. safe. Also, I have the extended cab if I need to haul too bags, etc. in the truck when hauling
signs in the back.
Another little option is I bought one of these:

The extend a truck, plugs into your hitch and gives you several more feet to use. With my tailgate down I can haul 10'
signs, with the extend a truck I have hauled 16' panels no problem. One job in particular I had to haul (8) 3' x 14' aluminum panels that bolt on the sides of dump truck beds. Prevoiusly, I had used a trailer - much easier with this setup and when you're done you just un-attach it from your hitch and throw it in the bed.
