i have a 2011 Rockwood 8281SS and i am wondering if anyone added a heat register in the master bedroom, i am thinking of using the plumbing that heats the storeage area below the bedroom but i am npt sure how to get it there, also the placement of the heat register in the back bedroom
gets covered up when using the fold out bed, has anyone address this issue
any help would be great
thanks
