Hi whp4262, I emailed Heartland customer service, got a call back, told me they don't have blue prints of their slide out for my 2011 Road Warrior, I ended up fixing it myself, I cut out a 1'-6"x2'-10" piece of rotten plywood out of the back corner till I was into solid wood. Used epoxy, fiberglass mesh and screws to install a new piece into place. Going to paint a rubber coating on the bottom for the slide out today.If I figure out how to down load pictures I'll add them in. Thanks Dave B
