You may want to look at this as a more permanent fix to the Velcro problem.

In my 16 years of experience with TM velcro flaps, it always seems the "re-applies" last for shorter and shorter periods of time, especially if your trailer is exposed to temperature extremes (in my case, heat).
I've completed the "test" of this on several camping trips now, and I am convinced this is the way to go.
