If you’re looking at stuff in that range, have a look at Tiffin’s entry-level class A. They’re really nice quality materials and not too far beyond an optioned Thor. I was blown away, as soon as I topped the steps of one.
I looked at Tiffan's and do not believe they come close to the Challenger. The Challenger has a high quality wood and great floor plans. The Tiffan seemed dated to us and we really love our Challenger, which is Thor's top of the line gaser.
I would be surprised if you could find a nicer gas coach then the Challenger, especially if you are staying under $180,000 MSRP. But if I was going to look at any other large ones in the gas line-up I would at least check a Newmar.
