Easier to run over a kid when backing out of a parking space in Seaside. I guess the determination of this being a pro or con is in the eye of the beholder.
con - worse gas mileage
pro - you can live in it and travel the country
pro - teaches you to live simply, without a lot of clutter.
con - no real bathtub and usually the showers are made for short people.
con - it is much older than your current vehicle and may not be as in good of a condition.
con - you never know how many stinky people have slept in your bed before you bought it.
