Hello! My wife and I recently purchased a 2015 Columbia Northwest / Somerset pop up and it has a electric roof lift system. I grew up camping in pop ups since I was a kid and they all had manual cranks. The people we bought the trailer from told us the lift never worked on its own on battery power and they always used shore power to lift it. I confirmed this and It won’t raise, the motor just clicks but never turns. The trailer is equipped with a marine deep cycle battery and my initial thought was that the battery was just low. Well after charging it it still doesnt have enough juice. My second thought was to get a battery with more cold cranking amps, but most batteries that are higher rated aren’t deep cycle. I read about doing a 6v battery setup but from my understanding that would give me longevity but not initial amp strength. I also thought about adding a second battery in parallel, but I’m not sure that would give me enough amps either. Can anyone offer any insight? Are there any places I should check in the mechanical lift system for resistance, ie greasing areas? Thank you!
