WOW- 100 nights/year observing in a dark place
Hard to beat=we all envy you
An RV just for astronomy/star parties
is a poor and/or expensive investment
As a life style and family trips also
That did not include the trips in the motor home so that would add another 15 or so.
Being retired, our family trips always are planned around the new moon. Our vacations are always to some place where the skies are dark and clear. That's because my wife loves the red rock country of the Navajo reservation and the expansiveness of the deserts.
Now one might think that our vacationing to these dark skies would be a sign that Jon "wears the pants in this family." But that's not the case. My interest in astronomy began more than 30 years ago when I met my wife and we spent our vacations traveling the back roads of southwest. That's her passion.
At some point I thought to myself, "Hey Jon, you ought to buy a telescope, it'd be something to do at night." So when I saw at telescope I could afford at a garage sale ($5), I jumped on it. I probably got taken but after washing the dirt off it and cleaning it the best I could, discarding the broken down mount and strapping it to a worn out department store tripod, I had myself a 60mm refractor with one eyepiece and no finder.
I just wanted to look around and see what I could see. Early one morning out on the Arizona desert I stumbled a faint, tiny bit of nebulosity. I didn't know what it was but I knew I had to see more. Of course it turned out it was the Orion nebula.. that was the beginning... These days, I'm pretty much doing the same thing, just going and seeing what I can see.
