...I'm curious: by "high rent", how much are you paying? We're paying $840 + tax for 8 months on indoor heated storage with unlimited electric, for 22-foot long space. That's just over $100 a month. many years ago in the same facility, our rent was at the $699 for 8 months + tax. But over almost 11 years storage, it climbed precipitously up to a staggering $840, for 8 months of indoor climate controlled.
Wow, that's cheap! For climate controlled without electric here in SC it's $300/month for a 20' spot. Outside exposed to the elements goes for ~$150/month.
My HOA has a storage lot but not enough spaces to meet demand. Luckily, I have a spot large enough for my TC and is only $150/year. So the TC sits there on saw horses until the day before I'm ready to load up and hit the road.
However, my next house after I retire will have room to build enclosed storage for a TC, FW, boat, and the truck. That way the place will look the same when I'm home or on the road.
