How we stay of gird longer?

Staying off grid for as long as possible is everyone's go. Van life. This is how we stay off grid longer. You could say it's almost a little hack that we've picked up while traveling for two years. But I am a rock and water bottles that we've had for a long time have lasted us. We always make sure to carry spare bottles and try and park by water. This just means that our tank water can be filled up multiple times while we're staying in one place that we'll stay for a long time. Now just to let everybody understand, we don't drink this water from the river. We simply use it to do our dishes and shower. We do use a filtered funnel and we also add water purifying tablets into it. The only buy bottled water that we'd thought water to drink. And eventually, we will get a life saver because that would make sourcing safe drinking water even easier and help us stay off grid for even longer. But for us, this is the way we stay off grid longer in those park ups that just feel like home.
