With hot batteries, it will probably just start right up and run. If it builds air for the brakes, (see air pressure guage) or just wait for the alarm to quit screaming, check the brake fluid, and if the brakes work, it shifts and has a good clutch( critical for slowing down if brakes fail) I would fuel her up, put on some hearing protection and just go for it. I did this twice myself, one from Salem Oregon to Portland, truck did 55mph on the freeway no problems. The second one wasn't as good, it was up in Idaho and I drove it as far as lewiston/clarkston, where both the brakes stopped working,,and then worse, a seal blew on the tranny, spewing oil on the clutch, disabling it. I pulled over and went and got a dumptruck to tow with, long story. drivers license rules for Oregon only No CDL if under Gross vehicle weight of 28,000 lbs deuce is only about 17,000.
