I have never seen a definition of exactly what any manufacturers mean by "4 season." The big thing is that I don't think there are any government or industry standards to use that term.
Do know, however, that even if your unit is protected against the weather, you will have a very hard time finding a place to stay in cold weather. I drove back to Michigan and Ohio last November, and even though the really cold weather had not started, I could not find an RV park with full hookups because they shut the water down to individual sites in early November. In addition, there are problems with dump sites being available. None at the individual sites were open, and only one in each park was available. Hard to get a water fill up also. And that was before the ground was even frozen!
I do know some people park trailers or motorhomes, and build skirts and put bales of hay or other insulation around them on private land, but I think you still would have to worry about getting water and dumping tanks.
My water tanks have heat ducts coming from my front and rear furnaces, but the compartments are not insulated, so that would not really prevent freezing at much below an occasionally chilly night--maybe briefly down just below freezing for a few hours.
