RV shopping? Run away from water damage!

By Russ and Tiña De Maris
Shopping for a preowned RV can make good financial sense. There are plenty of things to look at when shopping, but in our experienced opinion, the very first one is this: Watch out for water damage!

Where does water damage come from? The obvious answer is “water,” but the source of that water may not be so obvious. Water from outside the rig is often the most damaging; but water from inside, leaky plumbing for example, can cause problems, too. When inspecting an RV, do the “top-to-bottom” search method.

When you step inside the RV, first use your nose — you shouldn’t smell mold or mildew. If you do, there are problems afoot. Many folks will simply turn on their heel and walk away from something that smells.

Nose test passed? Look up as you walk through the rig. Notice any discoloration in the ceiling? It’s a tipoff to leakage – but don’t limit your ceiling checks to what’s immediately visible above your head. Open all cabinets and take a good look at the ceiling inside. Roof-to-sidewall leaks are often hidden in cabinets or closets. Any discoloration is likely a sign of a leak.

Lower your sights, and this time check around all windows and anything else (e.g., range hood vent) that makes a hole in the walls of the rig. Many RVers aren’t aware of it, but windows need periodic maintenance to keep water from seeping into the rig from between the window and the rig sidewall. Warped wallpaper or discoloration is again a sign that there could be a problem with water infiltration.

Finally, get down low. Peek inside lower cabinets in the kitchen and bathroom. Open spots where equipment is located. Look for any sign that water has been where it should not have been. Step on the floor wherever possible – it should be firm with no “give” and no soft spots. Leaky plumbing can drip onto floor level and run downhill.

What if you find evidence of water leakage? If you really “love” the rig and don’t think you’ll find anything else like it, then you have a decision to make. It’s probably well worth the investment of having a qualified RV repair technician take a look at the rig. Water damage not only looks bad but can compromise the integrity of the rig, rendering it useless or costing seriously large amounts of money to repair. Mold and mildew inside a body cavity can send out spores that can create health issues. Buying a rig that has water damage is a gamble, at best.

Worth looking behind seat back cushions and under bench seats, especially in corners.
Also, look for anything mounted in s strange position. We found rot behind a smoke detector mounted on a wall in a corner! !!!!

Look along the seam joining the cab to the body. This seam is subject to failure because these components do not move in unison. Speaking of Class B &C RVs.

What about looking on the outside first? Check for signs of delamination…wavy sidewalls or front or back. I realize a person could have delamination “taken care of” but as you do your first walk-around, that is a sign of water leakage.
