My camper is almost always ready to bug out. I can load it on the truck in under 15 minutes, fill with water as I load the extras that are stored together in the garage. Everything has a place, so it's not like reinventing packing every time. Rarely do I load the perishables at home, instead we stop at the grocery store on the way. A few perishables, ketchup for example, are the packets from McDonald's stored from past trips and in the garage fridge in a soft sided cold bag.
When I return home, I top off the propane, clean the tanks and do the laundry within a few days. All clothes are dedicated to the camper, so no packing there. Same with bedding, linens, reading material, etc. I have a vacuum sealer and I imagine it would keep stored dog food from smelling up the camper. I use a ziplock bag that works just fine.
I'd say 30 minutes from the time I start until I roll out the driveway unless I'm gonna tow the Suzuki Samurai.
It is better if I start the fridge the night before, but not a necessity. Usually cold enough by the time we get out of the store on the way.
