Stop in for a cup of coffee

Morning, need to get on my Dodge truck hard. Thinking about doing Sick-66, wife thinks I'm nuts.
I’d drive my w200 on that but not sure I want the gas bill. 5 mpg down hill in neutral on a 20 gallon tank. Last time I drove it to Indy, I had to fill up to make it back home. And that was only a 60 mile trek
