Could someone who's used knapsack please clarify a few things for me? I've gone to their website and didn't find the info i'm looking for. I want to know if, on knapsack you can plan a roadtrip the way you can with S&T. Specifically i'm looking for the ability to factor in driving times, fuel consumption, rush hour, road conditions, and scheduled rest stops and figure out where I'm going to be after eight hours on the road and book a hotel for the night. Do they update construction info? The website says it updates itself, but doesn't way what's in those updates. I'd also like to know what anyone's found the pros and cons of this program to be. Thanks!
