Yes it is a trailer and a camper
The state of Alabama does not require a title for a 1990 pop up camper. A title for a pop up camper that is more than 20 model years old does not need a title. If it is newer than a title is required.
We have a 2002 Rockwood pop-up camper which we bought used and are in the process of selling it. Should we have received a title when we purchased it in 2003?

The tongue weight of a 1999 Coleman Santa Fe pop up camper is 183 lbs - "hitch" weight, the specs call it.

Some brands do, some do not.

That would depend on the size of your camper. I have a small pop up camper and used my 2000 Jeep Grand Cherokee (V6) to tow it from Chicago to Yellowstone and back. I will never do that again. I now have a 1995 Grand Cherokee (V8) that tows it with no problem.
That would depend on if someone is offering a replacement pop-up canopy for your Winnebago camper. A very good place to check for this would be eBay.
