The Full-time RV lifestyle can cost a lot less than traditional living if one is mindful and budgets accordingly. To be truly frugal, one would have to keep traveling at a minimum, as RV’s are not known for fuel efficiency. This is one of the reasons we volunteer and stay stationary for 1-3 months at a time. It allows us to be of service and trade time and labor for our campsite. Since we own our motor home, we essentially have no housing expenses during our volunteer stints. Given our set expenses, ideally our monthly total is less than $2000 per month, not including taxes.
