hello, i am an active duty navy service member who will be driving from jax FL to whidbey island WA next weekend, i believe i have a good route picked but came across this site and figured i can never run short of advice. Some things to know i am on a bit of a time crunch thanks to the movers, but will have my GF with me as a second driver. We plan to start the 10th and absolutely need to be there by the morning of the 18th but much sooner is our goal. I myself have done a solo drive from jax FL to connecticut and back in the winter and 2 shared drives from jax to new york and back in the summer, all completed same day as departed, however that was east coast driving with frequent ability to stop for fuel and lighted roads i understand this will be much different. I currently have it laid out that our first leg is from Jax to dallas TX, stop for the night/day and take a full 12-18 hours to rest (i should mention given we are both navy we are quite used to a 12hr work shift and then only 12 hours to rest), Then take a easier drive the next few legs with day 2 being dallas to denver, stop for 12 hours or so then denver to boise ID, same stop and then finish it out last day to whidbey island. Google maps has this being a 14hr first leg, 2 12Hr legs, then a 9hr last leg but of course this is under best conditions/no traffic/no stops. The GF and i plan on trading off every 2-3 hours as she has never really distance drove before. My main concerns is fuel stops between the dallas to denver and denver to boise legs, it appears to go through some very flat/desert like areas and my car is a 14 GT mustang that at best on the highway will reach about 250 miles a tank. I should also mention we will have our cat with us which is why partly why we dont want to drag the trip out and would rather try to get it done quickly but safely. looking for advice and input on if there is a better way to get to WA, i would prefer to avoid the northern route that google throws at you right away and has you go through dakotas/montana for what seems like forever.
