I was surprised that the actual chassis of the truck, when they were being built at the Freightliner plant, was bolted together.
To get the "basement" in the RV, they make the chassis in 3 parts, the front frame, rear frame, and the middle "dropped" frame. The middle section simply bolts to the front and rear frames. Granted, it used big bolts, and a bunch of them, but it surprised me. I would have assumed that the chassis would have been welded, and braced along the top. I guess the welded floor section of the RV braces it enough.
Was certainly interesting to see how quickly they can bang them out though. Personally, I'd just like one of the bare chassis rigs to drive around on - that looked pretty fun as they drove them out of the factory.
Thanks!
