Good to see you're getting your jeep into jeep territory RKL! :)
On mileage, when I was still working I was doing around 25k/yr, much of it because I was driving from the coast to here for my rentals at least once a month. Probably close to 30k/yr the last years while my mom was sick. I have my trucks as a business vehicle on my taxes though, so the majority of the miles and fuel, plus maintenance and depreciation all get deducted, so mileage for that was inconsequential.
Mileage now is a lot less. If I was just doing around town stuff, I don't think I'd put more than 7k/yr between both vehicles. Given the multi-state road trips and fishing trips though, I think I'm around 17k/yr.
