Welcome from Colorado: A 1999 Excella 28' is a very nice Airstream travel trailer. You can go anywhere with it in good comfort, home away from home so to speak. Airstream trailers tend to last a very long time. We have a 86 Limited 34' and a 75 Overlander 27'. Neither are as nice or as well built as your 1999, but still good enough for us. Here is a photo of the Overlander out traveling in the Colorado. Let's just say it is important to stay on the road in Colorado. We spent the night here.
