I notice a lot of you say not to buy a brand new rv unit. I'm "assuming" this is because it takes a while to shake all the right-out-of-the-factory bugs out of it and locate all the problems associat...
Buy what you can afford. Whether it's new or used, cash or credit, big or small.
The best way to buy is to buy what you can afford AND what you will use. If buying new means you can't afford the fuel, then buy used. If buying used means you can't enjoy being inside the RV, then buy new.
There is no overall BEST way to buy an RV, but there are many individually wrong ways to buy an RV.
