Ok i am a satellite installer and i have a contractor topper plus gear and other crap. I just got this truck and its only a 1500. So can i just add a leaf or something to help it hold more or help it hold whats in it? Is the a big difference between a 1500 and a 3/4 ton? just wondering if i could get a 3/4 ton truck rear end and go? or is there more to it? any suggestions? lmk me know guys!
