Seeing as how you brought it up, have you test driven one of those giant Land Cruisers? Sounds like it might be your best option, given your choices.
I had a series of small, fuel efficient cars for years before I bought my Suburban 6 years ago. It's overkill 95% of the time, but there's also something kinda fun about overkill! And for those times when a full size vehicle is helpful (like dragging around a bike on a hitch carrier) it's a nice thing to have.
You've got that AG200 for fuel efficiency, maybe take another look at the big SUV?
Good luck on the search, hope you find something that works for you soon!
