There is an adage that says you can never have too much truck, and as much as I love Honda's (we've got 4 of them), the Toyota is a better tow vehicle.
That Ridgeline is basically on the Odyssey chassis (I believe?), since our Odyssey has the same towing capacity.
I guess a lot depends on how much towing you plan to do. While both will handle your trailer, you would probably be shortening the life of the Honda (and you said you keep them a long time) because it's really not designed for the kind of work. Of course, if you only tow occasionally, it may work for you and the wife.
I think I'd suggest looking at a "Certified" Toyota that is a year or two old, which would be in the price range, and since you're talking the previous "style", it's a proven system.
Hopefully, 67 doesn't mean that you're limited to another 10-15 years on the road.
I love Honda, but in this case, I gotta say the Tundra is better for towing.
