Q. We have an Itasca Sundancer 29-foot motorhome with a rear bedroom. My problem is at the rear wall; if you look down at where the wall and the floor meet, you can see daylight where they have separated. I thought about using silicone sealer and bolting through the outside skin below the floor and through some angle supports, but I don’t know if this is wise. Would that cause the outside skin to crack? Is there supposed to be flexing ability at the floor and wall joint? What’s the best way to fix this?

A. This sounds like the expansion strip that transitions between the back wall and the bottom of the floor isn’t covering, but it could be a more critical structural problem and should be taken seriously. Such a problem can occur when towing something with excessive tongue weight, or a load that’s too heavy for the rear frame rails.
My contact at Winnebago Industries suggests that you call the company’s Owner Relations department at (641) 585-6939, or your local Winnebago or Itasca dealer, to verify the motorhome’s chassis and coach model years and have an opportunity to evaluate it and recommend a repair. According to my contact, the factory can check engineering prints, verify what’s happening and even supply manufacturing drawings and a “fix” recommendation. — J.J.
