I travel for months at a time but have a "real" property to land at, so not completely nomadic. YMMV especially if full-time.
> share their general setup
I own a mid-sized SUV that gets 25-30 MPH. Think RAV4/CRV/Forester/Rogue/etc -- it's all the same just buy whatever you can get a good deal on (definitely RAV4 hybrid if you plan on lots of city driving; otherwise financially it's a wash until you get to $5/gal or so).
- bed platform in the back.
- Passenger seat is converted into a desk.
- onboard storage under the bed, in the back foot wells, and a battery in the spare tire well.
- outboard storage (including spare tire and water) on the roof rack. Solar panels over that stuff. Ran a cable from the panels to the battery.
- I have a little tent setup on the side which is nice when you have a place to land and want to... stand up.
> monthly costs
When on the road, I make due on about $500/mo and live quite luxuriously. I eat out and drink, even. Not counting the cost of the car or health insurance.
That number is going up over time due more to lifestyle creep than inflation. I try to keep my monthly expenses below one twelfth of 4% of 30% of my liquid post-tax assets.
> any tips/tricks/advice?
People spend stupid amounts of money to avoid renting and dependency on others.
Don't buy a bunch of shit. Instead, invest and rent!
Case-in-point: showers. You can blow $50K extra to have a setup that gives you indoor showers. Or, you can buy notes and have 50000*.05/12 = $200/mo = at least a few showers per week AND you get to keep the principal!!! (and that's just the winter months -- for the cost of one hour/month of cold water showering for 9 months you get an extra $1800/yr to reinvest!)
If you are young and single, anything bigger than Transit Connect is unnecessary. Honestly, I've seen people live in priuses for years at time quite comfortably. As that number as gone up, so too have the number of lobsters/cocktails/burgers/dates.
Try not to work from the car. A transit connect or RV beats an SUV you want to work from the car, but I promise you would prefer to work from a coffee shop or by following the weather and working outside as much as possible. You'll end up avoiding work days in the rig even if you have the space, so why blow stupid amounts of money? You live out of a car; I promise you won't want to also work out of a car.
