I did my first week in my driveway just to see how things worked for me, as I work while in my van.
Then I went about a hundred miles away for a week. I learned that my solar panels (free standing, not mounted) storage was really a sucky place, as it kept me from using the rear of the van for cooking and stuff. I fixed that with help from my friends in KY who helped me figure out a better place that left my cooking station free of interference.
I also learned the limitations of my solar system with two days of very little sun. Thankfully I had made friends in the campground and could recharge off of their electrical sites.
Beware of feral cats! They will steal your steak right off of the grill
You don't even see them in advance.
Bug netting/mesh screens were a godsend where I was camping.
Carry an extra chair to loan to a creepy camper so they sit at their camp rather than yours while calling you waitress endearments.
Next trip was 600 miles out and I learned that my fuel pump was bad and my tow limit was 10 miles
Either have a cash cushion or an empty credit card for emergencies. Relax, this too, shall pass.
Remember to carry your suitcase if you are changing climates, lol.
Get to your site before dark, in the rain, down Mr Toad's Wild Ride roads
If you're traveling through a major city, expect an accident and a delay, causing you to miss your camp arrival window (see above)
There is no Google Maps setting for "avoid nerve wracking conditions" - it's okay to pull off and settle your nerves, particularly if you learned to leave earlier due to above mentioned delays.
Some Walmarts clean their parking lots with very loud leaf blowers at 330 a.m., followed by the street sweeper dude.
My next journey next month is over 2,500 miles. I expect to learn a whole lot, and to meet a lot of wonderful people and see some cool things. I'll let you know what I learn that trip
