Apparently, I have poked somebody's balloon. "IF" I was the moderator on a forum such as this, I would be careful to give well documented advice. None of this, "I did such and such and got by with it" stuff.
When a new guy buys a trailer and comes to RVnet for Tow Vehicle advice, should he be told that manufacturer's ratings are worthless? Is that good for the new guy? I realize that the forum is mostly populated by experienced experts, but I think about that new guy who just wants a safe reliable towing machine without considering tire, suspension, or ratings upgrades. What number will work for him? Not "what might work for him". Take your choice.
