Just a thought. I was wondering if the Kelderman airbags would raise the truck enough with a 3500# camper on it, that if I dropped the hydraulic legs of the camper and then aired down the air bags would I be able to drive out from under the camper without having to play with those dam pump jacks. Oh ya! I should also disconnect the turnbuckles and elec'l connections I don't load and unload the camper a whole lot because it is a pain in the ass me no questions, but if this were an option I might be able to justify the expense to Mrs. Mgmt.
