Just before I left on my last trip, the city forced me to move my motor home across the street so they could complete street repairs. Unfortunately, I hadn't trimmed the tree across the street and ended up tearing the curbside edge of the rubber roof in two places and adding a 4' long gouge to the curbside slideout awning.
A roll of EternaBond was the solution to avoiding a long delay before starting the trip. A couple of 8" pieces fixed the roof tears and a 2' piece, split lengthwise, repaired the awning. A factory technician checked the roof repair a couple of weeks later and said that it looked like it was put on by a dealer and would last for years, a lot longer than needed before full repairs would be done.
The remainder of the roll of EternaBond is now part of the RV emergency supplies kit.
