In 2007 stated driving from Alamogordo NM to Warner Robbins Ga 1545 miles each way. I have made this trip, there and back 15 times, pulling our '62 double bed Overlander, or our '63 twin Overlander, or the ,73
Sovereign rear bed. Our truck a '91 Dodge 3500 4x4 srw cc with a 100 gallon auxiliary fuel tank. At 17 miles to the gallon, and a cooler full of drinks and an other with food. Our best time was 22.5 hours and longest time of 36 hours. At the time I was an over the road truck driver I have since retired and now it takes a week. It is so much better sight seeing and beach combing and eating off the land.
