I would highly recommend this kit for anyone who wants to start building highway trucks. The frame is already put together so you don't have to worry about getting the rails straight. The tractor goes together very well. Everything fits this is what I love about Revell models they go together with out having a bunch of problems. It is a great kit if you want to do some detailing and make it look like the real thing. I built mine in about three weeks. I took my time and enjoyed building it. Here's a few pictures of the end result. Have fun and enjoy the build.
