Just posted this on another thread a couple of days ago:
We live in southeastern Michigan. We purchased a Boler
17 almost three years ago and immediately purchased a cover for it as we knew it had leaks
. We've been systematically fixing the leaks
along with other issues, and soon will start camping (and evaluating).
Anyway we bought the Boler
1700 version of the elitemotoronline ShieldAll™ Travel Trailer Camper Cover W/Zipper Door Access on ebay. They also sell a version that fits the Trillium
13 under this name: ShieldAll™ Trillium
RV 1300 Travel Trailer Camper Cover W/Zipper Door Access.
We have used this cover almost three years, 365 days per year. It has survived 3 winters, and we are going to push it one more. At this point it has a number of rips, and we've been repairing with clear gorilla tape after cleaning the area with alcohol, applying the tape using a flat, firm backup surface, then burnishing the patch with a plastic putty knife. We have caused most of the rips while putting it on and taking it off. I would say that it works fairly well, i.e., the zippers still work, the door access curtain is effective, the three adjustable undercarriage straps work well. Also the upper portion and top of the cover has a soft lining thus protecting the exterior finish of the camper. Also, the cover is designed to fit fairly well with elastic along the bottom edge front and rear, together with the adjustable undercarriage straps.
I would say that considering the relatively low price, the cover has performed well. However, if you spend two, three or four times as much, you well get a much sturdier cover that will last much longer...
