I also have this cover: 69970 ADCO Travel Trailer Designer Tyvek RV Cover - 15'1" - 18'
It's through its first summer, coming into its second winter. However, it's not holding up well in the Arizona climate; I expect it won't make it through another summer. It's faded dramatically, getting very thin in certain areas, the straps are becoming brittle, and even on the reinforced corners, they are rubbing through and tearing (and we have a lot of wind a lot of the time) at the corners of the trailer. The trailer is 14' and the cover is quite large, so there's a lot of room for it to blow around. I did find some great stuff I ordered on eBay that's 3M corner guard stuff. It's not pretty but so far it's helped dramatically and comes in different colors and I will be ordering more:

I just pulled the backing and stuck it on all the corners. So far it's stayed stuck and it molds to the corners nicely. But I did finally concede and my buddy Brian Willard at Carver Covers is custom making me a cover made of Sunbrella material. Look, he said in the AZ (or any hot) climate, all of the cheap ($300 and under) covers just ain't going to cut it. With my 2005 T139, if it doesn't stay covered when not in use, the caulking along the seams rots and then one has to contend with water damage.
I bought the extended warranty on the Camping World cover, but unless it tears at the seams, the warranty doesn't cover tears from corners or sharp edges. Thusfar the seams are not ripping.
So... you either have to make the decision to replace a cheaper cover every few years, or suck it up and drop some cash on the good stuff. My boyfriend always tells me "Buy the best and only cry once." This Camping World cover is cover #2, and I've now got $500 invested in covers, minus what I'll pay for the custom Sunbrella cover, so I should have just bought the pricey one from the get go and called it done.
