I purchased a used 2006 5th wheel...how long can I reasonably expect it to last.
There is no expiration date on your RV. In theory it will last forever. Parts of it will rear out or become non-functioning and will need replacement. If you own it long enough, you may face a repair that costs more then the RV is worth, but after that repair, the RV will be usable again. Therefore, it can last forever. There are covered wagons, the original RV, still serviceable today. Not practical, but still serviceable.
