Go to my profile enlarge the picture there are no mods other than a mor ryde hitch plate. yes i do have the max tow haul package no sure you could get it any more level. I will say that we never put anything in the bed or cab and its just the dw and I. This setup so far has worked very well for us. Yes the payload is 1952/1957 truck is in parking lot. No I would not go any heavier or longer. The f'ver is a hornet 257rl. When people ask can it be done I try to give them my information just as anybody else, this is my experience. The best answer is gather as much information and then make a decision based on that.
