as with many if not most things, the quality of construction/components coupled with the quality of care given over time are critical .... the more components are used, the quicker they age .... we picked ours up on Halloween Day of 2005 .... it has been in use for 6 - 8 months a year every since .... both AC's, the frig, central vac, washer, dryer (twice), springs, shocks, spring hangers, all three slide motors, couch, both recliners, entertainment center (twice), fireplace remote (three times), Fantastic Fan, door lock, generator auto switching control, kitchen and bathroom water fixtures, and several sets of tires have all been replaced .... other components have been repaired .... many mods have been added, the most expensive of which is a Bigfoot Auto Leveling system .... the camper itself was ruggedly built and continues to perform well .... in short, if you start out with a well built camper, are willing to take care of it, and replace components as needed, it can last you a long, long time
