The campervan we had gave us about as much room as in our 13' Scamp
(sans tow vehicle). I won't lie, it was a challenge for the 3 of us to find space to "park" our luggage along with the bulky bedding, kitchenware, hoses, camp chairs, etc. I have to say the van was well stocked, almost too well with toaster, French Press, coffee pot AND teapot which we never used! We were glad to have each packed one 22" duffle and one daypack each (yes, for a 4-week trip). Everything was carry-on for the planes and gave us, barely, enough room in the van!
