We got a cover for our ROO back when it was new in '07. Started thinking small, but with DH woodworking equipment and RC airplane stuff, there was no room for my little convertible in the garage. Design kept growing and think we ended up at about 26 x 36. Seems like the cover installed was right at $3000. The downside was that our property slopes toward the pond, so we had to build a retaining wall on 3 sides and fill and fill and fill and build some more and fill some more. So glad we did in August!!! Think the final bill was around $6000, but we feel like it was worth every penny. Only thing we didn't do was to have a partial wall at the back, so the rear bunkend needed the decal replaced after 7 years. Going to check into some remedy for that by spring. Our new TT is not only longer, but has a deeper slide...makes getting my car undercover more of a challenge, but the cover protects Rocky, my car, a small utility trailer and a huge log splitter. We have plenty of slope for any snow load - not likely in West TN but it's there. My only concern about the fabric would be that it would not last very long with the sun/rain/snow, however, much less costly.
