I have been reading and reading many of the build threads. So inspirational! Seriously

My first and major question and I have not yet seen a build thread on this idea, so if there are some please point them out.
What I would like to do, still in earliest planning stages, is to build a Tear Drop design but have it removable from the trailer frame. The trailer would need to do other duites such as haul building materials, transport motorcycles etc...
I am thinking possibly a "landscapers" style trailer (they are fairly plentiful around here). I envision a Tear Drop appx 9-10 feet long and typical width 4+ to 5 feet wide.
Size in part defined by the frame size.
Do you think it possible and feasible to build a self contained unit that could "slip into" position and then be bolted down when used as a travel trailer?

I am an ex-woodworker, currently a dog trainer.
Appreciate any leads or thoughts on the concept.
Yours in road travel,
Eric
