Well I made it back from southwest AZ for the 4th time with my old girl. She has the Iron Duke under her hood. Somewhere around 2380 miles each way. 1300-1400 lbs.
Taught me a lot about coolant and trans fluid temp in the mountains.
She is now retired from towing my Burro
. Only expected to go to AZ 3 times with her but I didn't get my V6 Olds ready in time last summer for my new tow vehicle.
