[A/S] ?'s on 30-31' models

["guardaparque <tamangel@xxxxxxxxxxxxx>" <tamangel@xxxxxxxxxxxxx>]

Hi all, a few questions on the 30-31 footers. What year did they start 
putting beds (twin or queen) in the back (rear bedroom, side baths)? 
Also what is the difference between the Liner, the Sovereign and  the 
Ambassador 30-31 footers.?

Finally the ultimate question:

I want to eventually buy one, I like the 65-75 time frame, what 
suggestions for the best models?

Thanks in advance,
