All depends for us on the set up, while away for the last month, our quick overnight stay pack ups were less than 15 minutes and our 3 day pluses were probably close to an hour.
Quick setup is roll out kitchen, fold out soft floor tent, take kids stretchers off bed (beds stay made up) and put together fold out table and chairs for dinner and brekky. Turn on power and gas.
Long setup is awning and walls if required, and peg down tent, random fishing gear, kids scooters and toys, fold out camping chairs.
We set our camper up so everything has a place, needs to go on the trip and when things are pulled out, they go back without it needing to be like a Rubix cube relying on one thing on the bottom that you need until last has to go in first. Our last rip, even with two kids, we had hardly anything on the car and I had space in the trailer to buy a webberq and fit it in the trailer in Townsville.
We have a massive storage box on the front of the trailer that really helps.
