Here’s a cool little trailer that was in the parking lot for exhibitors this morning.
I just went online and found plans for making one of these at https://www.desertteardrops.com/
A little web research yielded that these have been around for well over half a century and::
Teardrops get their name from their aerodynamic shape, intended to make them easier to tow, although not all of them are teardrop-shaped. One trait they have in common, however, is their size: generally they are no more than 12 feet long and no wider or taller than 6 feet. Inside, there is room for a 54-inch by 78-inch mattress, just about right for two adults. Most teardrops have two side doors and a rear hatch that opens to reveal a camp kitchen or pantry.
