If you are a fulltime traveller it's really difficult. I don't know the details as it isn't super common to actually live in a vehicle here, but there are books and websites about how to make that happen, so there are some ways around it. I know more than a few retirees who spend winters in warmer climates, but they generally keep their homes in NL so they are registed there. One of my neighbours is away all winter in their RV.
To add to the 'this is how it works in Europe!'-page of this thread; I know a little about this.
Full time RV'ing is rare/non-existent in my country, but full time travel is not. If you plan to stay out of the country for over 8 months consecutively (some sources even say it's per calendar year, so if you do the last 7 months of 2019, then the first 7 of 2020 you should still be good but don't pin me down on this) you need to de-register yourself as a resident. This means you do not need to pay for national health insurance, do not pay any taxes (unless you have local income) but also do not build up any Social Security (which in contrast to the US is based on numbers of years you've lived here instead of how much you worked).
Most full time travelers I know just register somewhere else. If you have parents or grandparents that have no social benefits it's easy to register at their place and just compensate them for the extra taxes. I've done this twice when living abroad >8 months. As most full time travelers don't have any (registered) income it doesn't come with too many tax/benefits implications for the people already living there.
Another way to pull it off if you're a home-owner is to rent out your house while staying registered yourself (so pretending you're just renting out a room)
Usually the government doesn't check much, unless they get suspicious (e.g. living with your parents at age 40, no income or significant assets, yet no government benefits)
