The cure for towing out of level

Keep it simple...Why make RV'ing complicated when it's not.

I agree, it is alot of expense and complication to adapt that to an RV trailer when one can level the trailer by less expensive and less complicated means and it is better to be level, rather than depend on a huge amount of axle equalization to tow so far out of level.

Looks to me like a complicated and expensive way to solve a simple problem.
