BTW when Torklift found out I drive 6 months a year throughout Mexico a season, they also asked me to field trial their stable load system under more challenging conditions. 2 years of El Nino has made a bit of a mess of the roads down here, and it is also the country of over a million Topes (speedbumps). God knows what I will find in 3 weeks when I hit the area Patricia passed through. I am happy to say I like them a lot better than airbags. They help side to side stability, as well as raise the rear end of the truck, plus they can't puncture. I know I am starting to sound like I work for Torklift, but I don't. They simply make great RV & towing truck products and best of all they are American, not Chinese.
