Yes, it's really a 3,000 ft climb, I live at just about 8,500 ft (not 80000 - you added a zero in your post) and it's well known that Denver is the "mile high" city at 5280 (at city hall). That said, it takes about 1/2 hr to climb that distance so it's not a straight uphill, just your typical mountain driving - some steep sections, some relatively flat areas etc.

Thanks for all the input. I'm now ready to start looking at what may or may not be available in the area. I'll admit that I was first drawn to the technology based on reports of the Highlander Hybrid. The longer than anticipated wait for them to be available has been a bit disconcerting but I really didn't NEED to purchase a second 4wd vehicle before now. I have found a local dealer that lists a couple of FEH 4wd vechicles currently in stock (per their website) and I'll definitely check them out but I also am contacting local Toyota dealers to see what inventory they expect etc. I am not inclined to peorder something that I haven't seen, touched, and taken a test drive in. I haven't really considered the RX 400h as I just assumed the Lexus brand would be more expensive but I may check it out as well.
