Besides being great on gas com[ared to a large RV, a van is a great way to travel the country, especially when taking kids or pets. It allows room for everyone to move around and get comfortable and fits more than two people.
As opposed to tent camping, van camping offers much more in terms of space for packing and sleeping off the ground.
While the Jones may have a $100k Rv... their gas will likely cost near that as well... Keep in mind before buying a van for camping what the maintenance costs as well as insurance and and gas... Always call around to get best rates with coverage on insurance and plans can vary widely between companies but make sure you are also properly insured should you rear end the guy in the beamer in front of you..

Be sure, just as in taking any vehicle or motorcycle, that your van is in good running order and any issues are taken care of BEFORE you leave. Taking care of minor things wrong now may save you a headache on the road later.. Again, check your tires and fluids and engine for any strange new noises before heading out!
