If your ever in the Loveland, CO area look me up. I have the Maggiolina Extreme, and would be glad to show it to you. My wife and I are same as you in height. We love the Extreme and it measures as a small in the Maggiolina line up. I would think that the Columbus would be nice too, especially for warm climates and its lighter and easier set up/down. The Maggiolina is also very easy to set up/down but is heavier to mount on my truck each spring and off in winter (I like parking in garage during winter). Any questions holler!
