Howdy. I own a dodge 3500. I love the truck and do not want a differnt one. I own a lincoln vantage 300 and its sitting up front close to the cab and I have to be very carful when I turn when I pull a trailer so I dont hit the welder. I have been thinken about adding 3ft of extension to move my axle and so on back. My truck GW is 32,000lbs. I am usaly am overloaded and I probaly have around 50,000lbs. I think the best way is to cut the frame and create a v section then take a frame from a scrap yard truck and slide them up, bevel it then weld it with 7018 then grind it down after that take 1/4 floor plate to go over it with minimum 1-1/2ft past the weld on both sides and bolt it down with 8 3/4 bolts per side. Please let me hear all of your opnions. Im only 18. and experinces is a lil low for me. I am aware of lenghten cables, lines, etc and the driveshaft. and allingment is extremly important. I am at muskogee okholma and if there is anyone near me with the experince I am willing to pay for help. I just want it done right and plus there will be way more weight than anyone can imagine. Thank you.
