Prices start to climb quickly, especially when you want fiberglass. Whatever you do, stick to your guns and get fiberglass. We had 2 fiberglass units and our new TT is the corrugated siding. Big mistake on my part. It is just a cheaper and poor quality unit all around. You get what you pay for. The stability alone is terrible. We bought it on the fact that we wanted bigger and didn't want to pay the extra 10 or 15k for the fiberglass equivalent.
Our keystone Laredo was a great TT and we had zero problems. The outback and Laredo are just about identical, not really sure if there is a difference. I would put my vote in for a keystone product with a bunkhouse slide for sure.
