With Fourby Fitouts, choose a 4WD Fridge Slide that pulls directly out of your vehicle for easier access and a drop downslide that lowers the fridge to a more accessible height. Make certain that whichever sort of fridge slide you choose can be fully locked to prevent the fridge from swinging back and forth while driving. A fridge slide can also be used to transport other heavy objects, such as a generator or a large toolbox. Browse our best 4WD Shelf at.
