Here are some examples of Rock N Roll Bed frames that us at Camel Camper Interiors have built. There are also other frames here that we have been commissioned to build. As mentioned in our other sections, we truly can build these to any specification in any dimensions. Primarily we use 25x25, 25x50 and 60x40 box section in our builds. The smallest frame to date we have built was for a Nissan NV200.
