Camper means autonomy, but autonomy does not mean any limits. Water runs out, gas or fuel runs out, batteries run out. As you get used to shopping again when you run out of food and drink, you will also need to get used to managing energy and water independence.
This habit, which then becomes automatic like riding a bike, will come with use, but when it comes to buying a camper, choosing it, what should you do? Do you need attention?
It may seem like "the more water the better", but bear in mind that 300 liters of water will definitely overload you compared to your camper's 3.5 liters maximum, and you will then be traveling to countries with a load of water. then possible. Do you need that much water? In my experience 100 liters of water is the right compromise.
If anything, instead of adding water (and weight) I'd spend a few euros (less than forty between kitchen , bathroom and shower ) on setup (which includes replacing aerators screwed into faucets, this takes 20 or 30 seconds) waste ( like eco water and eco shower) ) is a simple and really effective method that allows you to limit
Built-in comfort is complemented by the presence of a heating system (stove) and a boiler for domestic hot water. The warm air from the heater needs to be well distributed in the cell, so check the position of the outlets and ask if the recovery tanks are insulated, this will allow you to go outside even in extremely cold conditions in winter.
If you buy a used one, especially if it's out of date, some manufacturers check the presence of the stove, sewer and boiler to make the purchase price more competitive, they made entry-level campers without these systems (of course declaring it was a choice marketing ) and leaving the possibility of establishing them after market interventions.
