I've repeated this before, it was once posted by a RV.NET member.
Question: What's the difference between an ATV and a rental RV?
Answer: The rental RV can go anywhere.
There are members who bought former rental units with good results.
Whatever you are considering buying, check it out very well.
This includes former rentals, privately owned or units from a dealer.
There are a lot of units available. Do your research before buying.
And, don't be in a hurry to buy. Condition is the important thing when buying a used RV.
Keep us updated on you decision.
