I thought Alpine was Keystone's top of the line. I know they discontinued Everest, that was the very first trailer my wife and I looked at. Just couldn't make a "deal" on it, ended up with a Montana Mountaineer.
I thought it was Alpine then Big Sky than Montana.
The second trailer we owned was a Montana, great trailer, only reason we let it go was I wanted (REAL bad) the 6 point level system and a few other goodies the Montana didn't have. I'm glad to hear they're offering the "G" rated tire upgrade. We didn't have that option when we bought ours, had two of the Marathon "E"s fail us. Solid trailer otherwise.
