Hello Stuart and Nonie,
Like you, we also looked at Airstreams and there is a dealership not to far from our house. We went down there a couple of times and knew exactly what we wanted, a 25FB... But after watching their forums and seeing all of the maintenance issues, along with needing to tow it with a larger Gas Guzzler that we have, our choice was easy and for the last 2 weeks, we've have been happily living in our new Oliver Elite II named the Lil' Nugget and we're still getting around 20mpg. Yesterday we made it to the Atlantic Ocean for the first time ever and we had started out on February 3rd from all the way over in California. So you can see that we travelled along way to pick up our new Olli and this was after many hours of researching all of the different brands that we knew of. In the end, it was Airstream and Oliver that were left standing, but there was really no comparrison between the 2. Oliver won,hands down, well ahead of any other competition.
We wish you the best of luck in your search and you have found a great place to get started :)
