Renting an RV for an extended time

My take is it all depends on when you plan to start this grand adventure, if you plan to do a week long test trip now, and then not travel for 9-12 months you may likely be better off renting, particularly if you can find an off season deal from some place like RVShare. I quick search of their site using booking dates in March for Florida, shows numerous less than 10 year old coaches available for under $1,000 per week. Which really is a deal compared to the cost of ownership of a 25+ ft class C of similar age if you are only going to use it a couple of weeks in the first year as just the fixed costs of ownership like insurance, registration, and storage fees can easily run over $1,000 per year before counting maintenance, depreciation, etc.
