Towing experts?

Most of my trailer towing is in california, where the car speed limit is 65-70, and trailer speed limit is 55 (of course, EVERYBODY does around 62)
Just cause your speed limit is 70, doesn't mean you HAVE to go seventy. Run at a speed that's comfy for you....... and make sure your tires are at or close to max pressure. (I have heard from several veteran tow-ers, that they run more than the max in their trailer tires.)
