Get the SUV option. Counter height is critical. I'm only 6'1", but I would HATE it if the counter were lower.
Save the money and do NOT buy AC. It's simply not needed in Northern California, or the west, generally. This is not Florida. This is not Michigan. This is not New Hampshire. We camped 20 days in our first year of owning the TD, and there wasnt'a single MINUTE that I wished we had AC, even when we were in Pinnacles, and it was 95degrees all day and was still somewhat warm at night. With the doors open, the screens in use, and the ceiling fan barely on, we were VERY comfortable. As Californians know, even when it's 100 degrees during the dayk, it ALWAYS cools off to under 70 at night. The only reason our homes need AC is because they heat up during the day (when you will NOT be in your TD) and because our homes do not ventilate well enough at night to get rid of the hot air. But the TD cools down very quickly once you open it up.
Now, if ytou plan to take the TD to Florida in the summer (which is crazy for many reasons), then I would consider the AC, no doubt.
Perhaps the AC could have some impact on resale value, if that is a factor for you.
Being in the west, I would buy the supplemental on-board braking, since we have serious hills and mountains. That's a better place for your $, I think, than the AC, for the buyer in a western state, particularly Cali.
Just my opinion, obviously. If I lived in Florida, Michigan, Boston, I might want the AC.
