The way I maintained a extra vehicle was, pick a day, every week or two and drive it all day. Get the fluids running, wheels turning, battery charging, etc. That also was a easy way for me to justify the minimum insurance payment, tag fee and property tax payments.
Also nice to know that I had a backup, in case the main car was out of commission for a few days.
"Also, I am looking at something with the 100k mark on it or more. I plan do the 100k service to whatever I get right away. But, what else might I need to consider along the way?"
I would look at something that you feel is reliable enough to make the longest camping trip your going to make.
