Do you guys have any pics of how the other companys are doing it? It seems from what I have found class 8 trucks arent available with a long wheelbase. By that I mean I want to have a 20' box after the cab. I was thinking of using the same size C channel to extend the frame then getting a samller size C channel that will fit in the existing C channel and basically box it in like
I have seen where people just add a new section of frame and seems like they just weld a fish plate <> where the frame is added but that seems like it wouldnt last.
Also I have seen plenty of class 7 trucks that are exactly what I want in a chassis just the engine is a smaller cat or cummins at only 250/300 HP. I think that will hurt the milage and the point of doing this. I want a big truck for safety/power and reliabilty.
