It adds up quick, especially for those of us who both dry camp and occasionally have full hook ups. Different hardware for each set up some times to a point. We recently sold our travel trailer and bought a toy hauler and there is actually less cargo space but more cupboard space. The less cargo space is a good thing I think because a lot of the things that were in the travel trailer did not make it into the toy holler. But then again some of those things weren't needed because the toy hauler has a lot of extras built-in.
