Has anyone ever extended the cab just behind the drivers door ??? has anyone ever thought about doing this ?? im 6-2 and 300 lbs and I need some leg room . I have thought about doing this but not sure if it would work . i would like to add about 12 inches . I don't think using a cab from a other truck would work because the turn is so short at that point . I know I would have to build a custom top and have a custom canvas top made . but as for the metal work I have never did anything like this but I think I could do it if I went ahead and tried it . but wanted to know if anyone has tried this and if anyone could give me some info on this ideal ????
