Worked with a couple of the kits and just aquired my third one. I have finished one and it was promptly got ahold of by my youngest. I did up a review of the kit in general which is here.

It takes alot of patience to build it up but does turn out pretty good. There are some minor things you can do improve the kit easy enough. Things like useing some brass rod to make new grab handles that are more to scale, extending the exhaust with some aluminum tubing so it actually comes out from under the truck, getting a real light bar or bubble gum lights to replace the chrome lights. I can't remember where I have the pics from the one I actually finished, but here is a link to one I am making into a tiller truck, a bit of a long term project. Might give you some ideas.
