Travel Supreme's best years

Hello to any Travel Supreme owners past or present. I have researched a lot of 5th wheels for full timing and after seeing and talking with a few owners near me, I have pretty much decided on trying to find a well taken care of Travel Supreme. I am looking mostly for a triple axle Select or Classic model, but would like to here pros or cons for some of the 2 axle 36 foot models I have seen. Are they really light enough for 2 axles? Also, I have found information that around 2004 or 2005 Travel Supreme started using aluminum for framing. Can anyone confirm this?

I would like to get as new a model possible that still has excellent workmanship and had the fewest problems since they went out of business.

Thanks for any information or experiences good or bad.
