Minutes if that. I store it right in the back next to my fridge and my dry food cooler, the stand is on the side of the bed right accessible too. So I pull into camp, drop the tailgate, slide the fridge out a few inches, set up the stand and the flip the lids open on the camp kitchen. We've cooked meals for 4+ adults on it, its tight but it works out nicely. The propane stays hooked up and there is room inside to store a second propane bottle.
The fallback it has are the cleaning factor. The grill is right over the aluminum and the tray has a 1/2" lip all the way around it so brushing out food is a pita. The grill comes off easy and the burner assembly clips right out so its not bad once your back home and ready to do a thorough cleaning.
