Hello,
Welcome. I have found that being close to a freshwater source(s) to refill is good. Also a place to dump the wastes for free. I have a grey and black tank. Wish the place I dump at was closer or in the same city I boondock when working remotely. But it's all good. It works out because the driving to and from - alternator charges the house battery back to 100%
For me parking at community centers, official county park parking lots, marked public parking spaces/lots. There is street near a creek i like parking at. So I a have a few spots. One of the spot there is a class c and a trailer I always see there. But they move around too in that same street.
It really helps that the city you are in the police won't hassle you-us, van lifers.
And it's good to not be long term. For me it's two, three night tops at the same spot before finding another (known) place within the same city.
