When we first began to full-time we had a fifth wheel with a big living room slide but without a bedroom slide and only shirt closets. Within 6 months we traded it in for a fifth wheel with the big living room slide and a bedroom slide so we could have decent hanging space. I also put wire shelves at each end of the closet. We didn't pack a lot of clothes but enough we used all the space we had.
So I would recommend you look at a bigger rig with a floor plan you can live in. It's really important that folks realize that fulltiming is a lifestyle and it is NOT camping.
