Yeah, I debated getting a small trailer for the SS itself, even looked at one of the tear drop ones that you can sleep in or making one of that expedition tent mounts for trailer. But I've got the cargo / toy hauler now (worked on roughing in some more plumbing yesterday, starting electrical today).
That being said, doing it all over, I would have bought a small motor home and an open trailer for the SS because I could have used the MH by itself when I needed. (I also go to Renaissance festivals.)
The Slingshot should fit right in with the 'Renaissance festival' …
