those little trailers sold by northern tools or harbor freight for the frame of the teardrop, this is a really good idea for a couple reasons. first, it just makes for a lot less work on the building side of things, your frame is complete and you can start working on the actual teardrop its self. and second, when you use one of those trailers you wont have to do the dot inspection just to be able to get it registered so that you can get plates for it. its not a big deal to pass the inspection its self, but if your like i am, every time i go
