Yea- unfortunately gas mileage is not its strong point. It's a 1988 so it is fuel injected which helps a little bit. I averaged about 11-12 MPG on the highway which wasn't too bad.
I didnt make it down your way but i did get as close as Prescott where i nearly called my girl friend and told her to send everything i own. I finally found a place where everybody dresses like me and drives trucks like mine! I made a month long trip out of it so i was in no hurry to get home.
My girl friend wanted to fly out to meet me while i was in the Prescott area so i told her to get a flight to Pheonix or Flagstaff or maybe even Las Vegas. Well...she called me and said she got a great deal on an airline ticket...to OKLAHOMA CITY...the next afternoon!!! One VERY high speed run later i picked her up in OKC and promptly bought her an ATLAS. Her excuse was "I wanted to save you money so i took the cheaper ticket." Then she looked at her new atlas and realized she had made me drive one third of the way across the country in about 12.5 hours.
Oh, well...what can you do.
The worst part was getting the oil changed...once in LA, once in Flagstaff, once in Kansas City and again when i got back to Detroit...spent $100 on oil changes in 1 month.
One of these days i will move out that way, somewhere in the southwest. My kids are almost grown now so i'm counting the months.
