3Fivers51, I agree from your pics it looks like a bad design. How ever I think you are not going to get any help from Jayco. If it were me I think I would do one of two things. Hire a carpenter to redo the existing cabinets or do it myself. Life it to short to worry about little speed bumps like this.
Now I know this might sound a little harsh but then again it's your problem not mine. It's not my hard earned money that was spent so it's easy for me or anybody else on the forum to give advise. Good luck and keep us informed as to the outcome of this.
