We haven't done it yet, but have looked into it.
I'm retired US Navy and every military base I've ever seen has a secure location for storage of personal vehicles, boats and RVs. It would be dry storage but I'd feel good about leaving our home on a military base. I might have to pay for a full month storage, but it would be relatively cheap.
We've also met folks who needed short term storage and found a local RV park would give th a good price for a week or two storage.
We are also Thousand Trails members and many folks leave a rig at a TT location for a time, from a few weeks to several months.
Something else we have done is leave our TT at a friends gome, where it can be plugged into electricity and driven a few hundred miles for one/ two night visits with family members around Dallas, Houston, New Orleans Shreveport/ Texarkana.
We seldom have time (or desire) to pull the trailer quickly on a loop to see cousins, etc. leaving the rig with our friend is easier. I make sure to pay him a little for the electricity and his time checking in the rig. We also buy him and his wife a good dinner.
Certainly cheaper to than 1,000-1,500 miles towing. And a lot less tiring than driving that much in a week or 10 days.
