I have a 32" three side closet shower it is enough room for me [6'-1'/232#]... if I have a guest in there with me... it seems to speed up the showering process rather than taking all the time....ah...."necessary"....bunks over the cab are usless for me as there is only about 16" max of space to romp around in and I need more because of my back and chicks don't like cracking their head repeatedly on the ceiling.The "attic" is good for storing crap that you really don't need anyway.....If I were you I'd go with a smaller unite and a trailer......geof [then again I'm not you
