These recommendations and suggestions come from some of the most knowledgeable individuals in RV Trailers and towing that you’re ever going to find. This knowledge only comes from years of hands-on experience, reading and watching what others do, and having a general interest in safe RVing. (Us)
(Them) RV dealerships hire sales people; it would be a rare occurrence for one of these sales people to have ever owned a trailer or even pulled one farther than the fairgrounds for an RV open house. Some of the specifications they quote may be true, but do not work well in the real world of towing. Also, in my opinion the same would apply when requesting information from a vehicle manufacture. They have a whole room full of $10 an hour workers answering phones with a frequently asked question cheat sheet they refer too. The chances of talking to a real engineer or anyone with actual technical knowledge are zero.
It also comes from many of us making the same mistakes over the years and trying to prevent others from doing the same.
