Please give me a list or tips for opening the camper for the first time after a winter outside. I need to clean off the roof, I think I read Simple Green and a Magic Eraser will do this. What else do I need to do? Look for? We are basically brand new to this older/vintage (? how old does something need to be?) Coleman Laredo. We spent a couple of nights in it last summer, then moved out of state, and I had surgery, and well, its just been sitting out there looking forlorn. We hope to take it out for spring break in a few weeks, and know we need to pop it up and check "things". Just not sure what those things are or the best products. Thanks for helping a newbie out!
