The sway control comment reminded me of my absolute hairiest moment I've had. The ex was following me in her wrangler, I was pulling my TT with my first truck, a Ram 1500, which did the job well but wasn't a 2500 if you catch my meaning.
Going down the highway headed home from a week out she was spotting for me with family radios, all I heard was the first half of watch out left!
Guy in a 24' box truck passed me going probably 80 to my 55. That set up a wave, it shoved me over and then sucked us together, the ex said we couldn't have had but a few inches between us. I'm usually pretty calm but that set off all my alarms.
Same trip, outbound leg. Rainstorm like you wouldn't believe. Go to get gas, take the off ramp, hit the brakes and nothing. The truck ABS is going nuts trying to stop this, the trailer brakes are soaked and not home right now.
Up the ramp I decide to just shoot across and take the on ramp, get back on the highway and figure this out. No bueno, there's a concrete divider there in the center of the intersection. Still gradually slowing down I go for broke, I turned it, left across the intersection, across the bridge, get it slowed down and pull into the gas station. I'm not sure, but if you told me the inside trailer tires lifted off the ground I wouldn't be surprised.
Steam is literally boiling out of the trailer brakes. Thank God that there wasn't any traffic coming, he really does look after children and fools. The rest of the trip up I'd drag the brakes a bit before the ramp to dry them out, that cured it.
That trip was the second or third time out with the new TT back in 2002.
Odds are I'll come up with some more suppressed memories of near disasters!
