Yosemite,Redwood n.p.

I have owned a 19.5' mini motorhome and went w/ 2 kids and a husband for 3 wks. Then a few other short weekend trips. I lived in a 5th wheel for 7 wks coming back from ALaska. I have a gotta have list,, and the most important thing I know is storage... closets mostly. One for me and one for my hubby. Then basement storage for things like folding chairs and bbq grills,, and off season clothes. I have 48 acres w/ a house that I rent out so we can put a storage pod on for the extras we don't absolutely want to throw away...things we might need at some point... After than less than 20 ft'r id think that a 30 foot anything would be a great starter rig.

any comments appreciated
