I sold mone last year, but I had mine since 2006 I guess. I got mine for 3500, bit it was like a deal through the outfitter i guided for and Jumping Jack. I have, I'd say, a years worth of nights sleeping in that thing.
Buy the extra cover
If its wet when you put it down to go home, leave the "included cover" unzipped towards the back. Set it up at home and let it dry. Jack the front up high at least while drying!
Set it up once a month, to make sure its dry( see a pattern?)
Don't forget to put the rear "foot" up when moving it or going home.
You WILL eventually buy another canvas. DON'T buy the " canvas is the same but the color is off so its cheaper" version. Spend the grand. 1150.00 or so with shipping. Otherwise the parts that dont mildew and mold will rot in the sun after a couple days. For reference, the good one is green on the sides, the other is so pale green as to be white. It WILL be white after a couple days in the sun.
Put skateboard skid tape on the tailgate or you will remove all the skin from your shins at least once. Especially if crown royal is involved.
Snow was never an issue. Loading a quad on it in the snow(or mud) can be....fun. Find a ditch to stick a tire in to lower one side, and load the from the side. Still less harrowing than loading the same quad in the bed of a lifted truck with a short ramp in the snow.
Buy the cover.
Never put it up wet.
Dont pay 8500. You can probably find a used Baja for less, still haul your quad, have heat and air, and take a sh*t inside when its snowing.
