My Tips - on the day you are going to move a frig - go to home depot and rent their truck with the liftgate. Also rent a good dolly 2 wheel truck at the same time. Grab a friend that has some muscle to spare. Take a bunch of blankets so you don't put and dents or scratches in it. Move old frig out into the garage for future keg-orator project and extra beverage holder.
Also make sure to measure the place you are going to put the new frig - the last thing you want is for it not to fit.
This plan worked out very nicely. Had the Home Depot truck and dolly back to them in about 2-3 hours.
