I unfortunately do not have a ladder on the camper ( on my list of things to get) and I need to get a Thule or something for the Excursion but I was going to do that for bikes. The underside of the camper is covered so I can't put it under there.
I could put it in the front basement but the dog pen and folding tables are in there.
Storage at home is not a problem, traveling with it is.
Thanks for the replies.
If your camper didn't come with a ladder there's a very good chance it cannot be installed after the fact.
