i REALLY liked the Forest River Rockwood highwall with the kitchen on the door side that i saw at RV show. except for the sofa placement., i asked if floorplan could be modified at factory. sales guy said no. dang. i would buy new IF i could get exactly what i want. so, used it is. who currently has this rig thats a few years old? how’s it holding up? how is the sofa attached? to floors or walls? both?
