I was having the same issue & was thinking about doing what Lynn1132 did. Everytime I'd go into an RV parts store, I'd look for a replacement. Finally while visiting MIL in Springfield, MO I went into one that just sells RV parts looking for something else, and found a replacement like they are putting on the new coaches. Looks & feels like rubber. It was kind of a pain to put on, had to take the handle completely off the coach, and put the new one on. I used soapy water to slip it on the handle. It was also "fun" to reinstall the handle, as there are springs in there that have to be in the correct location to work. All in all I'd say it was a fairly easy job with the hardest & most time consuming part was slipping the new one on. I did it on the picnic table at the campground. I tried to find it on their website, but couldn't,
here is their website, and it looks like they'll ship items if anyone is interested.
