A retractable guide for loading and unloading snowmobiles, ATVs and other equipment from a trailer or truck bed includes a first portion that is movable relative to a second portion that is fixedly attached to the truck or trailer bed such that the first portion pivotally moves relative to the second portion. The first portion is of a sufficient length such that when the first portion guide is in an extended position a distal edge of the first portion contacts the ground surface to provide a ramp for loading and unloading the ATV, snowmobile or other equipment. The ramp provides a smooth transition from the ground to the bed of the truck or trailer. Once the ATV, snowmobile or other equipment is loaded onto the bed of the trailer or truck, the first portion of the guide is pivotally positioned into a stowed position such that an end gate or other retaining wall can be positioned into a secured vertical position with the ATV, snowmobile or other equipment being positioned on the bed of the trailer or truck.
