I'm heading on a road trip in my van, but I am on a tight budget. Are there any good books for van living? Road trip on a shoestring ?, Strange and wacky sites and events ?

Where are the safest free spots to sleep ? truckstops ?

Is there a list of free campgrounds in the US ?

I'm thinking of getting a Koolatron cooler, but I am concerned about it draining my battery if I leave the van for a day or 2, what are they like ? In the mean time, I'll stick to jugs of ice

Any advice is appreciated

Thanx
