Update to the post....on the Friday of my trip, I lost the front outer wheel bearing just about Nashville, TN. Spent 3 hours in an O'Rielly's auto parts parking lot changing out the bearings and having the rotor turned.
Only other problem was on I-35 heading into Dallas, stuck in traffic moving around 5 mph for about 2 miles...the engine began to foul out spark plugs, sputter and die. Waited around 20 minutes, cranked the motor and drove on into TX without any other problems (have since worked out issues with the carb "after" I got home).
Mileage overall for the trip was around 13 mpg. On the way up and back (nice level roads, no large mountains to travel over) mileage was a tad over 14 mpg. Overall mileage round trip was right at 3700 miles!
Should y'all ever get the chance, Hot Rod power tour should be on your bucket list to do. You meet a lot of nice people out on the road!
