That fancy new big 5er is for all intents an empty space, therefore a vacuum, and you will soon fill it with what you really need plus things, gadgets and otherwise useless 'stuff' you might or might not ever use ----- someday. Oh and we went from a truck camper, two fairly small TTs, a medium size 33' 5er and now a 4 slide 38 footer so have become experts at filling empty spaces
