Hi seaotter -- I could take several positions with this answer and take flak from some quarters. For someone anticipating a lot of miles and pulling a heavy slideout Airstream, I couldn't think of a better solution than the Hensley. The Hensley
patent has expired and only
this vendor has jumped into the gap -- it remains to be seen what his service will be in the long run. I know that I am seeing wear in my 2005 Reese Dual Cam purchase. Short answer -- Hensley supports their product. Can you go wrong? Compared to the overall investment in tow vehicle and 30' SO, I don't think so.
