Doug, we have had our 28RKBS for a year now and love it. We fell in love with the floor plan as soon as we stepped in. Is the one your looking at brand new or is it uses?? Just look it over real well, turn everything on run the water in all your faucets, climb up on the roof and check out caulking around all vents, sky lights, front and rear caps....
Hopefully everything will work out for you and you will be camping real soon....
