>>841701Doesn't sound bad at all. The disadvantages seem trivial and you'll get used to a small space. What about water for general use? Cant really take your dishes into a gym for washing.
Also have you thought about solar panels for the roof? At least to charge your electronics? Just an idea. Dont know if it will survive the open road.
Kudos for going offgrid. Living in a rapevan is my dream although i personally would have gone with pic related since i own a motorcycle.
