RVs are a far greater risk buying with a rebuilt/salvage title. As was mentioned above, flood damaged units that are insured get totalled and often they will be bought as junk by the unscrupulous, cleaned up, and retitled. Making a good, cosmetically acceptable repair on a collision damaged RV is usually too much work for the creeps so when you come across an RV with a new title, it's most likely a flood damaged one and it will quickly become a money pit for the unsuspecting buyer. Avoid salvage title RVs like the plague.
