ABSTRACT:
The invention as presently conceived discloses a variable length ramp system attachable to a standard pickup truck that assists with the loading of all-terrain vehicles (ATV's), small tractors, yard equipment, golf carts, and similar items. The length of each ramp can vary independently with the other from a minimum of approximately four feet to a maximum of eight feet. The extension is similar to that of an extension ladder in which once piece slides inside the other. A textile strap with connectors provides further securement of the ramps with the truck body. When not in use, the ramps can be collapsed and stored in minimal space.
