Will the Strait-Line Weight Distribution RP66073 Work on an Interstate 20 Super Coach Trailer

I did some research on your Interstate 20 Super Coach trailer, and found that the trailer has an 8 inch I-Beam frame and most likely an adjustable channel tongue. This is the reason that you are having difficulty with the weight distribution system.

It seems to me that if the sway control ball mount is hitting on the left, driver side when turning that the right, passenger side sway control ball mount extension would also be making contact when turning. If this is the case, we do not have a weight distribution head that does not have a sway control ball mount on either side of the head.

If you are not making contact on the right side of your trailer frame, the Strait-Line Weight Distribution, item # RP66073, may work for you if 4 inches from the center of the ball mount hole, to the outside edge of the weight distribution head will be sufficient to provide clearance. I have attached a photo for you to see the measurement I took from the weight distribution head. If you need the right side to be less than 3-1/2 inches from the center of the ball mount hole, then this head is not going to work.

I spoke with my contact at Reese and he said that you will most likely have trouble getting any weight distribution system to work with the 8 inch I-Beam frame and channel tongue coupler.

I have a 2010 Tundra with a Interstate 20 Super Coach trailer. Currently, I am using the Pro Series 49569 WD and are having problem. The head hits the channel on the left side. I removed the head from the truck, hold it by hand and placed it under the receiver, swing it and try to figure out where it hits. I found out anywhere that is more than 3.5 inch to the side from the center of the ball will hit. I am wondering what is the measurement is from the center of the ball to the edge of the left side of the head.,Thanks very much for taking time to look into my problem. My other question is, What if I use an air helper together with an adjustable hitch DTSTBM6600? Does an air helper kinda help distributing the weight too?

An air ride suspension system would help level the rear of your truck and the trailer for towing correctly. The Adjustable Solid-Tow Aluminum Ball Mount, item # DTSTBM6600, that you referred to will also help with getting the tongue of the trailer to the correct height. These items may help with some of the up and down bounce that you may be experiencing, but they will not distribute the weight from the trailer tongue to the vehicle and trailer axles like a weight distribution system does. These items will not correct any issues you may be having with trailer sway, and all of the tongue weight will still be at the rear of the vehicle, which removes weight from the front axle and diminishes steering, traction and stopping power. If you are not experiencing significant bounce at the rear of the vehicle or trailer sway, I would say that an air tide system would be a good choice in your situation. The Firestone Vehicle Suspension, item # F2445, is the correct kit for the 2010 Toyota Tundra and should work great on your truck. If sway is a problem loading the trailer correctly will help to reduce sway significantly. Make sure that you have the weight in the trailer distributed with 60 percent of the trailer weight forward of the trailer axles and 40 percent behind.
