Have a paid off van
In order to live by the river in a van, you must first have a paid off van. If the van is not completely paid off, paying monthly installments will be extremely tough on your budget.
It is imperative to have a solar shower in your van. The shower should consist of a 5-gallon bag to contain water and is heated by the sun. A good solar shower is going to cost you approximately $15. The bag can be hung on a pole or a tree limb once it is heated. However, you need to remember that a solar shower will not be a very long one but you will still need it.
Living space in a van will be cramped, which is the reason why it is imperative to have a screened room or a tent with you. These tents are easily available at stores like Walmart or Costco.
Auto Cool Solar Powered Car Fan
Living in a van down by the river can be an extremely challenging task in the summer. In order to cope with this problem, you can purchase an auto cool solar powered car fan, which should cost you less than $20. It will not drain the battery of the van as it is solar powered.
Eating & drinking
If the river is clean in your area, you can use the water for drinking as well as fishing. However, make sure that you boil the water and allow it to cool down before drinking it.
