I have had the rv for almost 4 years now and no probs to speak of!
I just had to clean up the light sockets for the rear lights though. Some water made it into the housings and rusted up things enough so that my reverse lights didn't work and one stop/turn light.
After cleaning them up I put dielectric grease in the sockets.
I caulked the housings with clear silicon also.
Still love driving this thing with no after market shocks or anything extra.
Mostly avg.9.5.
I still only have about 9k for millage though and I even winter camp 3 or 4 times a winter with it !
Which reminds me I need to clean up underneath again and touch up things with some paint like the bottom of the storage boxes.
Pulls the sleds and trailer like they aint even there..lol.
