When renovating a truck camper (or any camper) weight is key. Sure, wood and other classic materials are aesthetically pleasing, reassuring, and seem environmentally friendly. Yet, every extra pound means more gas consumed per mile. We would rather use that gas to travel long distances than to move heavy weights. That (and a lot of rot) is why we decided to replace all the wood in our camper with a fiberglas composite material. Not only is it lighter than plywood, it is also resistant to damp, mold, and fire. All good things! That means that we learned a lot about fiberglas, resins, and other lightweight materials.
