i rhino lined my whole 27' trailer, including 8" up the side......when wet, the carbides on the skiis would sink in slightly and the track would just spin, real pain in the rear...then i took some of the ez-glide strips, and laid down two tracks for each side....now the carbides won't sink in and the traction is sufficient that i only rarely have to pull the sled....i did this 3 years ago, and the inside of the trailer still looks new with no damage to the floor at all....and i use my trailer 2-3 times a week.....because there is no water leaking out of the floor of the trailer, the bottom is much better and there is no moisture at the junction of the floor and the sidewalls, which on a non-treated trailer cause perforation of the aluminum sides because there is constantly water at the junction of the floor and sidewalls....i keep my trailer in my rv garage where i can keep it heated and dryed out....if it were outside, i think i'd have to find a way to get a space heater and a fan to it....
