I am a huge fan of 2004 Delorme Street Atlas USA with Delorme Earthmate GPS
I have the version w/ the US phone book, comes in very handy...
map to phone number, call to confirm location, find old girl friends..,
I have been using a Toshiba laptop from Costco ($899 two yrs. ago)
Radar tab allows you search for truck stops or food ahead., That saved my butt at least twice.,
Under Advanced routing you can tweek it to your driving speed on various roads
( Interstate, main roads etc)
Very accurate, I am amazed over and over again when I get a run to rural nowhere at 2 am and when I drive to the red finish dot, stop and look around I can usually see my drop. Savings in time/fuel alone pay for a good GPS System.
Map is not perfect, but you can draw in roads that are too new to show up, you can not add Routable Interstate exits though.
I flag all points of intrest, scales, rest stops good buffets etc., handy when you go back a year later.,
