Hey folks - so this is my first post - I hope this is the most appropriate forum for my questions. Come this October, I'm planning on driving from Alaska to the east coast and then on to the west coast. I'll be sleeping in the bed of my truck on a platform under a topper. So my questions are...do I need to worry about condensation forming on the truck bed if I don't have a bedliner in it? I'll definitely be hitting colder weather and I don't want my gear to get soaked from any moisture that may build up. Also, without a bedliner, will dust and moisture make its way from the road into the truck bed? Has anyone had any trouble with condensation forming on the inside of a fiberglass topper without any roof liner? Many thanks on any responses!
