2: By set up, I just mean folding out the main tent and hopefully tightening a couple of extender arms. Usually 10-15 mins unless using an annex, which as you rightly point out, is more of a PITA, especially for short stays.
I'd say to setup the tent alone would nearly be = on 99.9% of soft floor trailers.. same for hard floor.
Softfloor - unzip travel cover - pull tent over, 2 uprights 2 extenders = you can sleep if need be
hard floor - undo locks, flop over floor, pull over the tent couple of poles etc done.
Caravan - pull up, dont even unhitch, sleep.
FWIW I'd never buy a new camper or caravan ever again.
