Very cool. Congratulations on that.
My sister and her husband both have Jeeps and *love* them.
There is a nice community around too - a lot of Do-It-Yourselfers.
With that and super long road trips in mind - you might like this book. I've had Haynes or Chilton's Manuals for all of my vehicles over the years and very good to know a few things - right down to being able to take it all apart if you really get into automotive mechanics as a hobby of sorts.
Very tough world out there these days, but safe and inspiring travels to you. Spring is almost here. : )
