I worked as a contract controls engineer (still do), and did a lot of startups & commissioning gigs.
I lived in a 40' 5th wheel, and enjoyed the flexibility. I could go from fully set up to fully set up within 24 hours. The flexibility made it a LOT easier for my employer to stick me into a gig, so the job security improved a lot.
The moves were not that often (every few months or so), so my employer hired an over-the-road truck to move the RV and I met them at the new site. It's cheaper than a week in a hotel, and WAY cheaper than paying to move an employee.
As an out-of-town resource, I still received the same housing and M&IE per diems as any other contractor (see your federal regulations on that one; there's charts for every major metro & surrounding area). This pays for the site as well as repaying the cost of the investment in the RV. (Investment--a thing where you spend money and expect to make money with the thing you bought. Like a carpenter who buys a good set of tools.)
I worked a lot of automotive gigs and found that there was NEVER a gig more than about 1/2 hour from a full-time park with Winter sites. Generally if you stay for a few months, they will give you a big discount on the slot, esp. Winter. Only one site didn't have sewer hookup (it did have electric & water), and the honey wagon came by every week.
I met some really great people full-timing in an RV; there's a real community out there. I've never had a bad neighbor, and the good thing is if you do, you can always move! Also, I met my wife while full-timing. We lived together in that 5th wheel for 3 years, and if we had an argument, there was no avoiding an issue by stomping off to the other end of the house. We pretty much had to deal with it then and there!
Some suggestions
You will need a "tax home" when you file your taxes and to maintain your driver license. If you qualify for residency in a state without income taxes, this is a good choice. If you move around a lot, get a forwarding mail service. This can also help with the item above. Personally, I used the post office of Mom & Dad. Every month or so they'd throw all my mail into a box & UPS it to me. If I needed something in a hurry, there was fax (ok, I guess it was a while ago...) and email.
If you plan to do this for a while, get a nice RV. If you live in rathole you will feel like a rat.
If you buy the RV new, have it prewired for generator, satellite on the roof and cable in the side. I used sat & cable both when I was on the road; cable is better, but SAT is not so bad. After you've done it a couple of times you can point the dish in about 10 minutes. I never needed a generator, so I never bought one. RV generators are not cheap, they're noisy, and the take up a lot of space.
If you need AC, get more than the vendor says you need. The folks that sell them lie. On the days you need it you will be very glad you got it. Either a roof-mounted RV unit (or two) or a window unit. You have to reinstall the window unit every time you move, but it's a lot cheaper and works just as good.
Water in Winter
Get some Raychem Frostex and heavy pipe insulation for your water hookup if you plan to Winter in a cold area. Dig out the water tap to below the frost line and run the heat trace and insulate. Buy a tankless water heater! I installed a precision temp RV-500, and believe me--a long hot shower in the middle of Winter is wonderful.
Heating in Winter
Don't get the tile floor. They crack up and are cold as hell. Do buy some good thick house slippers. I think we had "Uggs" or a knockoff like them. Thick wool sheepskin slippers. RVs floors get cold in Winter; your feet will thank you. Keep a spare furnace motor on hand. The DC motor has carbon brushes which are a wear item. Once they're go, you need a new motor. And they die when it's cold. Get the double-insulated windows, or just cut some Plexi to size and cover the windows on the inside. It makes a significant difference in the temperature and your propane bill.
