Abstract
Abstract of the Disclosure Title: LOADING/UNLOADING APPARATUS
For loading a snow-mobile onto a pick-up truck, the truck is provided with a tilting, slide-out deck. The deck runs on rollers. The rollers are secured to the truck bed, and are engaged by runners on the deck.
The runners are hinged: when the deck is pulled out, the deck, and a portion of the runners, hinges down to the ground. For loading, a gentle slope is required, and a ramp-extension slides out of its stowage position in the deck. For unloading, s steep slope is required, and the extension is not used.
