For those living in RVs, boats, and so on, can you comment on the amount of time you spend maintaining your living space? As a startup founder, as much as I am concerned about cutting costs, I am also concerned about the opportunity cost of spending time doing maintenance. E.g., even if you fully own a house, a house can be a lot of maintenance work. Depending on how you value your time, that can reduce how much you "save" on rent. Any comments?
