We purchased the toy hauler new and are non smokers. It is in good condition, receiving routine maintenance, and has been stored under roof in an RV storage facility since purchased. The rubber roof was replaced 2 1/2 years ago due to some minor tree branch scrapes on the outside edge, with no damage to the siding or roof structure. Due to the RV being stored under cover and living in Arizona, the roof never got wet. There is some sun fade on the front decal and a ding in the fiberglass caused when the vehicle was jackknifed and struck the truck cab. The faux leather on one couch recliner is cracking, with the other three in perfect condition. We dont have any pets that could have caused this so I have no explanation as to the cause. One of the six hydraulic leveling jacks has a slight fluid leak that appears to be coming from where a hydraulic line is threaded into the jack, and not from the cylinder. I do not have a wrench that is thin enough to fit on the nut and the leak is small enough that I havent taken it to a mechanic for repair.

We are selling this luxury toy hauler because we dont use it enough to justify the storage cost. If I used it more often, or had an RV garage to keep it in, I would not sell it.
