A few years back when pulling my fiver into a tight spot, i had to extend the slide. Everything work out fine, but when leaving this camp site, my REESE slide hitch would not retract to the normal on road tow position. I put blocks under the trailers wheels, and pulled back and forth with my TV but could not budge it. We were still about 200 miles from home, and just drove with the hitch extended. When we were about 2 miles from home, and coming up to a stop light, that slid hitch, and trailer, decided to finally move forward with a loud BANG. At first i thought that someone had run into the back of my fiver, but it was the trailer finally moving to it's proper tow position. When home, I dismantled the rails on the hitch, cleaned them, and found no problem that would have caused the hitch to freeze. When re assembling your rails pay attention to details, as it is easy to switch these rails from side to side, and those plastic pads are easy to come loose. The hitch is now 15 years old, and has worked pretty much as it is supposed to.
