Cliff, that would be hard list to populate, since so many builders have come up with their own designs or modified existing designs to suit their own tastes and needs...you have some of the original designs from MechIllus/PopMech which cover the Cubby and Trailer for Two, the Cub/Modernistic, the Benroy and then you have very distinctive designs from Grant Whipp, Camp-Inn, So-Cal and other manufacturers and these are followed by individual designs such as Mike's Weekender, our AlligatorTear and many others, that all copied or were inspired by others...and the list continues to grow by the day.......

p.s. by the standards of this board, "Teardrop" covers everything that you can't stand up in and USUALLY has a galley in the back, if you can stand up init, it will fall into the TinyTravelTrailer category which goes up to around 15' and has a single axle...as in all rules, there are exceptions and crossovers in these two categories.......MJ
