Keeping the fridge cold is the main thing. When loading, I pull the camper out from the back side of the garage and position it in front of the garage door. From there, I pull the ramp down (toy hauler) and we load everything from the back in about 20 minutes. (clothes, food, then golf cart, fire wood, kids bikes, etc. etc.) We prep nearly everything that needs to be loaded and then we get the assembly line going. Kids bring us stuff and we put it away and then off we go. Same with unloading. Stuff comes out of the camper, into the garage and then the camper gets parked and plugged in. The wife and I are starting to get our process streamlined. If i needed to run the A/C, I would bring the generator out and run it off of that to cool it down.
