First off, I'm 6'2" and I get into the smart car and move the seat forward.
I am still tandem and plan to stay that way. It has allowed me to get out of some "stuck" situations at least 3 times.
Depending on what your future plans might be with a trailer (I know, we all say this is the last one), your pin weight might be a problem, depending on what you do with a large drom (for extra storage of stuff) (especially if you don't have side boxes).
