Too ambitious-yes. You spend too much time in the vehicle and not enough time having fun. Figure roughly 50 mph on average, determine the number of days it's going to take for just driving, then decide if what's left is enough. Since you are talking over 2500 miles to get out there, it's a min of 5 days out and 5 days back. Put 7500 miles on a vehicle in 3 weeks, drove 4 straight days to get home and felt like I never had a vacation. Shift driving is fine but when on unfamiliar territory of nothingness it's very easy to fall asleep at the wheel, and with the shape the roads are in it will be almost impossible to sleep PLUS the most likely won't be able to be buckled in.
