By doing your homework and taking your time with the looking part of the process, you'll be on your way to making the right decision. Now that you've found the RV of your dreams, a thorough inspection is in the works. You might consider taking the coach to your family mechanic or some other third party for a complete once-over that includes an engine compression check, electrical and cooling system checks and so forth. A full road-test is also in order. When considering buying a used RV, open each exterior compartment and make sure all latches, locks and hinges function properly.
Water damage is one of the most common problems with older RVs.
This problem is usually worse in less-expensive rigs or those that have flat roofs instead of tapered roofs that encourage water runoff. To check for water damage, carefully inspect the entire ceiling, as well as the walls near windows, for any sign of stains, discoloration or delamination. Even minor stains on a fabric or solid ceiling will indicate that water has entered at least once. And where there's been water there can be rot in wood frame members, wiring corrosion, delamination of wall or ceiling panel materials, packed and matted insulation and other problems. Open each exterior compartment and make sure all the latches, locks and hinges function properly.
