We just recently purchased a 1994 Rockwood XL 1280 pop-up camper which currently does not have an air conditioner. We want to install a rooftop air conditioner, but we don't know if the roof can take the added weight. How can we determine if the roof of our pop-up camper can take the weight of an air conditioner? My husband read that pop-up camper roofs have to be built to withstand the weight on an air conditioner. So, we are not sure if we can install a rooftop air conditioner or not. Please help if you know anything regarding our situation. Thank you!!!
