Craig, glad I could help you spend some money!
You are off to a great start. I was once in the same boat as you. Had Tamiyas and while I liked them, I knew I would never be fully satisfied with them 100%. That's not to take away anything from the guys who build some wonderful Peterbilts out of the King Haulers, because they surely have talent - more then I do, when it comes to styrene - but I didn't think I would ever have the ability to create a truck exact enough for what I wanted. Besides that, the Wedico scale is a closer match to our die-cast tractor collections too. Welcome to club. By the way, you got a smokin' deal on that cab and chassis. Lucky guy.
