1500 miles here, I'm the only driver, last time, left late morning, 397 miles to central Missouri, (in December you have to know what campgrounds are open or closed), then 450 miles to Manchester, TN KOA, then 419 miles to Valdosta, GA, then only 215 from the Fort on last day, we could drive farther if needed. Our last trip, I unwinterized here, (Nebraska) day before we left, set furnace at 45-50 degrees. Same thing coming home, after we got home, left furnace on low until next day when I rewinterized it. I agree with bjschil, the newer campers are easier to do. Used to do the drive in 2 1/2 to 3 days but was burned out after I got there and needed a day to recover.
