I've had my undercover since early 02, and have had no trouble with it. It fits well, is watertight, requires no maint., and still looks as good as new.

 

Love mine. Had a problem with the first one (see gallery). Replaced free of charge, no questions asked. I would absolutely buy another. Not sure about actually walking on it a lot though.

 

All of my 195 pounds of fat stand on mine regularly when I wash the roof.

Jumped up and down on it a few times to prove a point to some naysayers. No problems.

I agree, mine is a year old and has been through heavy snow and rain with no problems. Im 288 lbs and I stand on it to wash my roof with no problems. (the main reason I got it) My 2 kids play on it also. Price is great and the best part you dont have to wax it.
