Here's a quick, printable, DIY online site I like:
http://www.mappingsupport.com/p/gmap4.html
To start, click on the Gmap4 button at the top. On the map, using the upper right dropdowns you can switch between several map types.
I use it for "boondocking" in the RV, hiking, and Jeeping. I used to print the maps on waterproof paper, but my old printer can't handle it anymore so I just use plain paper and plastic sleeve. I've never used the distance scale as navigation here is mostly terrain association, so I can't say how accurate it is. It's, at least, a good planning aid.
