To add to my story, we were on US 10 or "old 10" as it's also known. We were on the West side of the town of Baldwin approx ten miles or so on a stretch of road that curved and had a double hump in it. This set off one of the worst trailer sway conditions ever witnessed by those who scattered from their locations either behind us or coming at us.
US 10 was 3 lanes at this spot and we used all three before spinning 180 degrees and hitting a guardrail bringing us to a stop as the trailer flopped. No ticket was issued as the local fire dept. said we were not the first trailer accident at this spot due to the same sway issue coming over the double hump and through the curve. Comforting huh?
US 10 was closed for two hours while they cleaned up the 22 gallons of fuel and righted our trailer back to it's wheels. Which leads me to mentioning, do not fill your gas tank on your trailered vehicle if you can help it. Do it once you reach your destination, only you can prevent road fires!
