what are the pro's & con's of renting an rv?

Be sure to turn off the generator when in a campground. Seriously.. many people don't know that.

Pro's: 1.You get to wear it out before it finds a happy home.
2.Try before you buy, if you don't like it don't buy one.

A "C" is no harder to drive then a U-Haul. Make sure you get a complete rundown of all of the systems before you drive away. Figuring out how to light the stove when you are all alone is tough. Most of the rental RV's I have seen are beaters. They are the reason that the term "Drive it like you rented it" was coined. They are basic low end units.
