I think that this is much ado about nothing. Towing is like everything else: idiots will do what idiots do; the rest of us will read up as necessary and do it safely...
In short, I do not find towing to be much of an issue even with a tow vehicle that isn't really designed for heavy duty towing (minivan).
Exactly! In posting these interesting videos, I certainly did not imply that one cannot tow anything unless he has a pickup or an SUV.
Though my SUV has a factory tow package rated at 5000lbs, I have not towed anything approaching that. But in case I get a large TT, I would need such things that I do not have such as sway bars and a load-equalizing hitch. In researching the Web, I found these videos that were eye-openers for novices like myself.
I suspect that fish-tailing accidents are caused more by the tail, meaning the trailer, than the dog. Specifically, the user did not load the trailer so that its center of gravity is in front of its axle.
The guys I saw fishtailing on the highway had BIG pickups. This highway is a divided highway, with two lanes in each direction. It has many long stretches of 6% slope and, when crowded with camping weekenders, becomes a kind of race track where these guys are showing off their trucks. Yeah,
"my diesel truck got more torque than your puny truck". Pulling trailers, they have no problem passing my minivan, which I keep on the right lane, going up 6% slope.
My theory is this. The type of trailers most popular in this part is the "toy hauler". An enclosed trailer, it has a ramp and an empty tail end so that the user can drive up his off-road vehicle such as quads, dune buggies. It's fairly common for the weekenders to bring up 4 quads, one for each family member. So, he might have loaded the trailer tail-heavy, which caused the trailer to wag like a dog's tail. The saving grace was that their gigantic pickup could handle that tail. It's still not kosher, wouldn't you say? One time, as a guy with a wagging tail was passing me, he was tail-gated by another guy. I slowed the hell down to let them get far from me as fast as possible, as they chased each other into the sunset. Yes, the literal sunset, as the highway was westward back into the city and it was Sunday late afternoon!
In surfing the Web for RV blogs, I ran across a guy who lost his dually pickup and his fifth wheel to a roll-over. He certainly was a seasoned RV'er, and was not towing it for the first time. He blamed it on the highway being "grooved", the kind of longitudinal grooves that were cut into the road to enhance traction.
Now, I have heard of motorcyclists complaining about these grooves, but for these to cause a dually truck and its fifth wheel to roll over?
If I find it again, I will post the link. Though his big pickup and 5th wheel were totaled, he and his wife were OK. They climbed out and took pictures to post for their blog.
