Burning Man? Not I, but others have taken their molded fiberglass trailers to the festival. Iíve seen several old threads about how to seal up trailers against the onslaught of sand and dust.
Are you thinking of an egg-type trailer for your adventure? If towing might be involved, first question is whether you have a suitable tow vehicle and what itís rated to tow. The answers will be in your ownerís manual. Figure around 1500# for the lightest molded fiberglass trailers.
