After living in an custom van for 11 years, and being stranded as a caregiver for 15 years, I'm just now getting back out! And it's different this time: I have disability pay, and brain damage.
I can't work on my own vehicle anymore. Both pathology and physical ability-to-handle materials gets in the way. And while building my trailer was great fun, it has limitations: when you have no A/C, it'll cost $900 to get one. When it's merely busted, and need it repaired, it's far, far cheaper. The words "...for an RV" multiply the price of some things.
So now I'm starting to rehab a huge Class C- low gas mileage, but I can park it, and TOW a smaller vehicle.
I got on the road six months after buying (but not discovering) Donald Fagan's Kamakiriad album. When I finally opened it up, I was SHOCKED: a theme song for my WheelDwelling life!
It's great to see others that REALLY have lived on-the-wheel for a long time. Not just semi drivers and like you said, 'retirees who only go to the campground'. But now, I'm kinda headed the campground-way. I'm HAPPY to live alone, in a new city/state every month, going where I can go.
Now: to get my behemoth ready for the road, and get OUT of here!
