Skooter has me beat.
However I drove my 52 3800 from Virginia to California to Washington, on to Canada, back to the US, Chicago, Detroit, Niagra Falls, and back home.
About 8,000 miles, 28 days away from home, not all driving.
55 model 235 and 4.56 gears.
Only needed a generator bearing and a fan blade.
Never left the county with the truck in the several years prior..
Just get in it and drive. If anything happens take a moment, think of the adventure ahead, the stories to come, and calmly get on with fixing whatever you need to fix. Being flexible is the key to not worrying.
