@janet7 Can you find a motorhome or mini to rent for a short trip? That might be "just enough" without taking on the responsibility of ownership and maintenance again.
In most places this is the off-season, so you might even be able to get a lower rate. If I was doing this, I would camp close to home (or to where I rent) - maybe even in a favorite or familiar place so you can reminisce.

We too are experienced campers/travelers and recently bought a new pull-behind trailer. Even without MCI, it has been a challenge for the two of us to learn all the details of the new rig. Rentals usually have clearly posted list of how to operate each feature, and sometimes a number to call for help. And as you already know, other campers are the most helpful folks in the world.

Also, if you are on Facebook, you may want to ask in this very helpful group if anyone has tried this, and what their experience has been.

Are you willing to discuss renting with your husband? Maybe talking about the difficulty of storage between trips would be a selling point?
