Thank you. I did not talk to TorkLift directly, but a reputable local dealer did, and was told that they are never going to support frame mounted tie downs for a single cab (not crew or extended) because no one buys them anymore. I have emailed Happijac and they assure me that their tie downs will work, so I have ordered them. We will see if they understood that I have a single cab truck when we try to install them. Becaus I use my camper on rough terrain, I think Happijac will be more suitable than Brophys. I did have TorkLift tiedowns on my 2007 Ram 2500 single cab and was very happy with them.
