I second the others who suggest a shorter, stockier type horse. What you will want to look for is a thick horse with a wide chest, thick leg bones, and big feet like the pictures that have been posted here. A short back and a big barrel are also good indicators of weight carrying ability. I have a Mustang that is 14.3 and due to his thickness, I wouldn't hesitate to put someone heavier than you on him.
I am the same height as you, littlehoof, and I don't think I would go for anything terribly tall. For me, anything much over 15.2 gets difficult for me to easily mount without a block or a hill. A cob of some sort or a draft cross would work wonderfully, I'm sure. I am not sure about the temperaments of cob horses (I have no experience with that breed), but in general, draft crosses seem to be more mellow.
Always remember that feeling of looking at a big, open country over the ears of a good horse, seeing a new trail unwind ahead of you, and that ever-spectacular view from the top of the ridge!!! Follow my training blog: http://robertsontraining.blogspot.com/
