I'm not really a Hotshot, just a hauler. I pull trailers, anything with wheels, usually from manufacturers to dealers. I use a Garmin Street Pilot III, daily. Wouldn't leave home without it. Hotshot buddy of mine doesn't use GPS, just paper maps, atlas, that he has trouble reading. Just came to save my but when I blew up in VA. He came 400 miles to get me, went 100 miles wrong way because he misread his atlas. He runs 150k a year so you can do it without GPS. But I wouldn't, GPS. . . wouldn't leave home without it. All GPS are history books, soon as the maps are written the world changes. Best part about it is it will eventually work my way to the destination. I download address level detail for every destination. I've used GPS on a PC, for me it's not practical, bad enough using Laptop for log. GPS for me is fulltime, hence the smaller the better.
Cheers,
