Reduce hump and sway when towing
For the short 4 mile trip from my pole barn to the marina, a standard type III, 2 inch ball hitch is adequate. However, even with a 10 percent tongue weight I still get some sway over 55 mph. Uneven roads and passing trucks all increase the "pucker factor". I wanted a better setup for longer trips.

RV'ers have long known the advantages of using a Class III/IV, 2" x 2" Ball mount weight distribution hitch for heavy loads. RV trailers usually have electric brakes, but they seldom become submerged in four foot of water.  Weight distribution hitches from Reese, Draw-Tite and others are not certified for use with boat trailer surge brakes. The only company I know of that makes a weight distribution hitch that will work with surge breaks is the Equal-i-zer  lmade by Progress Mfg. located in Provo Utah.

I purchased the hitch from a third party vendor at a significant discount. Despite this, the manufacturer's customer service department provided outstanding support and advice. Their brochure showed the setup for "A Frame" travel trailers, so I e-mailed them pictures of the H260 "pole tongue" trailer, and they immediately responded with instructions for use on a boat trailer and answered all my questions. Installation was easy. I sent the Equal-i-zer  customer service pictures of my final installation and they came back with a couple of comments to help tweak it further. 

The product works as advertised. There is no substitute for common sense and caution when towing 6000 lbs, but the Equal-i-zer hitch helps stabilize the rig and I get little or no sway at any speed. I got a lot of experience with the hitch last summer and recommend it if you are going to do any long distance towing.

No, I don't own stock in the company -- I just think this is a well designed and well constructed product.
