So with site options pretty well ironed out, I turn back to considering which gear I'll take both for the eclipse and for night time observing on the way up or back.
I just ordered a pack of 25 cardboard and film eclipse glasses, for myself and others who show up at the same spot with me.
I also ordered some solar filters for my 7x50 binoculars, which will see both eclipse and night duty on the trip. For both the eclipse and and night use the binoculars will be mounted on a parallelogram mount. I'll also have a PST double stack in single mode set up on an alt-az mount for before, and after peeks if anyone wants. That's really it for the eclipse itself, I think - two tripods, two mount heads and two instruments. Though a 4" refractor with a solar wedge on its own alt-az mount is an option too, but I am leaning towards "less is more" thinking I'll probably be inclined to enjoy the eclipse naked eye and with the binoculars, both filtered and unfiltered.
For night sky observing I am leaning toward also keeping it simple - beefy, quiet alt-az mount with big, affordable, "richest field" 6" achromat and a only a couple of eyepieces (low power wide field well-corrected and medium-low power wide field well-corrected), and an OIII and UHC filter. Summer seems to revel in panoramic targets.
That'll also keep my cargo space ample no matter which vehicle I take. Still leaning truck, but car would be oh-so-much cushier. But in either case, set up and take-down would be minimal, which matters on the return trip since practically speaking I won't be leaving the eclipse site until around noon, after end of partial and loading up all of the stuff, and will be looking at a long drive home (or to a campground or hotel nearer to home) from the eclipse viewing site.
