Recommendation of Weight Distribution and Sway Control System for 4x6 Inch I-Beam Trailer Frame

Question:

My towing vehicle is a 2002 Chevy Suburban 1500 4x4. I just purchased a new flatbed trailer that I use for deliveries. My first problem is that the trailer frame is made from 4x6 I-beam, so I am not sure how to mount the brackets. Next problem is that I never have the same load on the trailer, and the trailer is loaded only half of the time. The trailers GVW is 14k with an empty weight of just over 4k. On average I would guess my normal load range is 3,000-5,000not counting trailer weight, and the most that I ever plan on towing is an 8000# scissor lift. Any thoughts?

I spoke with my contact at Reese and he said that you will need to use a standard weight distribution kit like the Heavy Duty Trunnion Weight Distribution System 1,500 lbs. TW / 15,000 lbs. GTW, item # RP66131, for your trailer with 4 inch wide by 6 inch tall I-beam construction.

To use the Heavy Duty Trunnion Weight Distribution System, item # RP66131, you will need to have a steel plate 5 or 6 inches wide welded, by an experienced welder, at 30 inches on center from the center of the hitch ball. Before modifying the trailer frame you will need to check with the trailer manufacturer to see if this will create an unsafe condition, or void your trailer warranty. Once the plate is welded you could then use the bolt on Weight Distribution Chain Hanger Kit, item # RP58305 to attach the weight distribution system to the frame. You will also need a Weight distribution shank, item # RP54970, and a properly sized hitch ball, item # 63836 with the weight distribution system mentioned.

With the bolt on chain hanger you will use the trailer tongue jack to lift the trailer tongue and the vehicle at the same time, to attach the spring bar chains. When the trailer is loaded light the spring bars chains will not have to be attached as high on the hangers. You will need to measure your vehicle, front and rear wheel well, and attach the chains so that the vehicle stays near its factory ride height with each significantly different load you are carrying. You will also need to adjust your brake controller for each load and road conditions.
