Also just installed the Blue Ox Trucenter on my 2016 31UL. Only drove around 75 miles but it was interstate and two lane back roads. On the interstate, 18 wheelers passing me did not cause a noticeable problem ( I was going about 68), in fact, several times I took my hands off the wheel and the unit steered straight
. On the two lane (no real shoulders), several 18 wheelers passed me going the opposite direction and again no noticeable problems.
The system has a button on the dash to press if the wind is steadily blowing you to one side but I haven't needed that yet.
Soon far I am pleased with the investment.
