Nothing incorrect by getting a TH even if you don't have toys. If you get the set-up with the 2 beds in the garage area that raise to the roof and can be lowered for sleeping, and then you if get the bottom bed that can be folded up to make a forward and backward facing couch ... wow! You got the best of all worlds: Extra storage, extra sleeping room, extra space, all kinds of possible configurations, couch for lounging, drop down that back door ramp, hang a screen and watch all of nature! We've considered Toy Haulers for a long-long time now, just never made the plunge yet. And we don't have toys either.
Go for it! Live the dream!
