Although there are times when I’d prefer a shorter tandem axle Airstream, over-all I’m happy with my choice to go with my ’92 Limited 34’. You will find true what has been stated above, that it is actually easier to tow and park the triple axle.
When I bought mine the PO had put a receiver hitch on it. I had issues trying to back into my residence RV pad since there is an angle from the street to the driveway, so I had to have the hitch cut off. Of course that had nothing to do with the trailer itself. I’m probably more conscious of turning corners as well as more careful about looking ahead to avoid sharp dips and/or turns than I was with my 31’ International but I’ve had no real problems.
My most memorable parking saga was in an RV park in Woodland Park, Colorado. It is heavily populated with trees and the internal roads are narrow. My wife didn’t think I could put it in the spot they’d reserved for us, but I did it with very little trouble. The Texan in the big fiver next door was very impressed.
I see no evidence of rear-end sag on mine.
