I do mainly welding repair work and have been slowly working my way up in the service truck world. I started out with my welder and gear piled in the back of my jeep, when I needed more room for tools and parts I would just hook my little camp trailer to the back. That setup got me by for a year and a half!
Then I finally bought a real service truck, I got myself a Dodge 2500 4x4
I ran that truck for awhile, and it worked out pretty well for me, but I had some ideas on setting up a welding truck a bit different than most. So when someone offered to buy the Dodge from me, I figured it was a good chance to try my idea. But unfortunately, I would be without a truck until I found the right one. So I spent a real busy weekend buildings a welding trailer to go behind my jeep
I ended up using that setup for the summer and was actually pretty happy with it. I was able to do everything I could with the dodge, the only drawback was that I went up the hills a little slower. After quite a bit of searching, I finally found the right truck. I ended up buying a Ford F450 with a utility bed and a 34' manlift that is also rated for crane work with an 800 pound capacity at full reach. It's not 4wd, and the interior isn't nearly as nice as the Lariat package Dodge that I had, but at the price, I sure can't complain! I've finally got this truck setup mostly how I want it, and so far I'm really happy with the setup and am glad I didn't go with a conventional crane.
