We recently replaced our Norcold with a Summit ff1112bl. It's about 23-1/2" wide, and approx. 58-1/2" tall (the exact measurements are online), so it wouldn't take much of a modification. It seemed a little pricey for the size to me, but it was EnergyStar and gave us quite a bit more space in the interior. We got ours from appliancesconnection.com, as they had the best price we could find, as well as free shipping; also found a coupon code to use with them; and they also gave us a small rebate afterwards for leaving a review. As an added bonus, since our Norcold was working fine, we sold it on craigslist for nearly what the Summit cost.
