Even if you think you might eventually buy, many RV experts recommend renting different models first, just to see what suits you [source: New RVer].
If you're truly unfettered and want the freedom to pick up and leave at any time, then you might be a candidate for buying. But buying isn't cheap. The RVs that come flush with upholstery and appliances can run more than $130,000. The good news about this price is that RVs qualify as second home tax breaks on your tax returns. But payments on $130,000, plus the regular maintenance involved, can cost you more than $600 per month [source: New RVer].
A rental, on the other hand, doesn't incur constant costs, but it does require some planning to rent. Also, you may not be able to smoke or take along your pets in a rented RV.
