Anyone carry a ladder?

I added a ladder to the back of the TT. On one trip I had a problem with the slide topper. I couldnt reach it from the roof, or ground. The neighboring camper lent me his fold up homeowners step ladder. I bought the same one. Its 4 feet and that allows me to reach everything i need to around the rig, all the way to the roof line. Stows nicely. Cost is $70 at the home center. Looks like this.
