Class C regrets/Options you wish you had?First time class C

I would go for auto levelers. We have a '11 Chateau 31k, with the mid-ship TV which works super good for us. We have replaced the day/night blinds and re-linoleumed the floor with 'wood plank' roll/sheet flooring, makes such a difference. We use boards, plastic blocks, but going forward, backward and re-figuring what side needs how much height gets to be a "discussion"!!!
