How many bother with a cover for their camper? I will be parking my camper on my truck outside full time in my driveway and wanted to cover it. It will only be used for camping as I have a commuter car. I am trying to keep tree sap, etc. off the exterior. I found an extra large SUV auto cover that fits over my pop up truck camper but doesn't cover the hood of the truck. I'm ok with that. One concern I have is that the vented propane door is covered up and am wondering if I should remove the propane tank and keep it in the garage when the camper is covered. The bleed valve propane could probably settle and escape as the cover is not airtight but I am still thinking what if? How many use covers or not?
