Sun-Fun Campers are strong all aluminum welded structure and frames. The exterior of the trailer is 100% aluminum and all of the parts are cut using a CNC plasma for accuracy, fit and finish.
The frames are insulated with cut fitted rigid foam insulation, then wrapped with an insulating blanket. All seems are sealed with aluminum tape to keep the trailer air tight.
Cabinets are a solid wood structure built for strength and are insulated for that added layer of comfort and sound suppression.
