Here's a different take on the question.
Background:
We have owned motorhomes for over 30 years. A year and a half ago we were between coaches, and rented a CruiseAmerica for 10 days. Apparently, they have been doing that for over 40 years, so they have some background, and have their coaches made by different manufacturers to their proprietary specs.
Go to a dealer and look at a CruiseAmerica coach, and compare it to yours. Everything that yours has and theirs doesn't, is something a renter will break, stain, rip off, etc. And look at the scratches on the sides.
NO:
TV
Slideouts
Steps
Satellite
Awnings
Front swivel seats
Carpeting
Rear view camera
Etc.
I'll bet you their flooring and upholstery are more durable and less comfortable than what yours has, for a reason.
They take a $500 cleaning deposit, and, according to our rep, many renters walk away from it rather than return it clean, holding tanks empty, and gas and propane full.
You don't say what your storage costs are, but, IMO, the cost of storage and the cost of ongoing maintenance in time and money, and the stress and expense of a new family member, I say sell it and buy a different coach when you are ready to travel again.
You can always rent a CruiseAmerica if the travel bug hits.
