Your not that far from Elkhart, Indiana - home of just about all RV makers and RV suppliers. Lippert (actually now it's called LCI) bought Kwikee and they have US headquarters there. If they can't do it, there would have to be half a dozen other places around that area that can help you out.
While going to Elkhart... have your slides adjusted and checked over. Get your RV's interior remodeled. Change out your sofa for theater seating. Get a new Paint Job. ETC, ETC, ETC. It's all RVs all the time in Elkhart, Indiana.
Oh, and the RV Hall of Fame and Museum is there too.
