Good points Don, but I think once a group gets into a groove the stops should work out for everyone. A lot of folks will probably have spouses or kids along, so the progress wouldn't be as marathon as typical for solo "men-folk". LOL!
I just drove my antique semi back from Kansas and made it in a little over three days to central Florida. And that was with three repair stops and only driving during the day. Of course, with 160 gallons of diesel I didn't have to stop unless I really had to stop.
With consistent road time I feel 3 days from Florida is reasonable. Most mapping sites have us shooting through Atlanta on 75 to eventually get to 70, which I just drove from south Jersey to Kansas. Lots of places to grab a good nights rest and scenic farmland.
So for us this looks like a vacation, depending on the munchkin's school schedule as the only wild-card if there's any important testing going on around then. Otherwise it'll be a family adventure! Although we'll more than likely bring only one VX despite the temptation to take both. Then again, if I land a nice step-deck for my big rig...
