I enjoyed those pics. Especially liked that Donahoe truck. Lots of very useful mods without going too "Pep Boys."
Just one change I would make to that truck, well two actually.

Although they are not "in," I like my trucks with a shell. Especially useful if you're hauling around a bunch of dogs. That leads to change #2. Is it possible to install a functional roll bar which will fit underneath the shell?
