During my RV camping years, I have pulled tent trailers, single axle holiday trailers, tandem axle trailers and fifth wheel trailers. Each one of these units exhibit different handling characteristics. Choice of tow vehicle determines what wind and a fish tailing experience can do. This heads a long list of safety concerns.
In the early years, my tow vehicle was always a car. As my trailer sizes grew, it soon became obvious that a car was definitely not the appropriate vehicle for a tow vehicle. Even with equalizer hitches and sway control, tow vehicle must be large enough to handle the load.
One weekend with a friend and his family, we drove west towards the mountains against a very stiff wind. My friend was at the wheel and was pushing the trip at a very high speed. We were in a Jeep Cherokee pulling a 30 foot bumper pull trailer without sway control, much against my recommendations.
At one point the trailer started to fish tail and swing wildly about on the busy 4 lane highway. Glancing over at him, I noticed that he was panic stricken with both hands clenched, his white knuckles in a death grip on the wheel. I yelled at him to slow down and to only use the trailer brakes which he eventually did. As the vehicle speed dropped, so did the wildly swaying trailer until it all settled down without issue. We eventually concluded our trip without further incident.
Once we were back home, the first thing my friend did was to purchase and install a full set of sway control arms. His report later was that there were no further incidents as he had learned to keep his speed under control. Fully utilizing the new safety equipment now installed on his unit provided for a stress free journey.
In conclusion, my friend has now realized the importance of safety. He presently drives a properly equipped Ford 250 pulling a 30+ foot fifth wheel. He realizes the choice of tow vehicle determines what wind and a fish tailing experience has taught him.
