We are new to the pop-up trailer camping world and just took our new to us 2010 Viking pop-up trailer out for a weekend trip. The electric lift works fine when going down, but it takes over an hour and a half to get it up because the power cuts out after only raising the roof an inch each time. We waited 5 mins and got the same result. Of course when we tried it out from the person we bought it from it work just fine. Unfortunately for us, we have tried it twice with the same result. Does anyone have any suggestions as to what night be at the root of it? Any and all thoughts would be most welcome.
