If you have 2 weeks, I would do a trip west. You can always go again when the kids are older to do the stuff they're not up for yet.
If you only have 1 week, I would do something closer. A lap around Lake Michigan is fun, stopping places like Door County Wisconsin, Pictured Rocks in the U.P...
I have a 2003 1500 on 35s, I get 12 mpg as well. Problem around here is the rust just eats them.
Main hunting truck is a 2014 1500, same hemi engine, taller gears and stock tires = 20 mpg.
Yours is a sharp looking truck.
The assertion of 95% accuracy is where they lose me. Easily disprovable by looking at their predictive odds from last year then looking at the actual draw results. It's their best guess, which isn't worthless, but definitely can't bank on it.
I also sometimes see new hunters posting here wanting to do a DIY backpack elk hunt, and they never have shot that doe on the back-40. Talk about jumping straight into the deep end.
