Patent ID: 8602713

Claim:
An apparatus, comprising: (a) a rollable frame, said rollable frame movably steerable in both a forward direction and an aft direction substantially opposite the forward direction; (b) a lift assembly operably attached to said rollable frame; (c) a cradle having a first side and a second side and a front and a back, said cradle operably attached to said lift assembly and configured for supporting an auxiliary fuel tank; (d) a first user operable hydraulic system for raising and lowering said cradle between a first generally horizontal plane generally in line with a generally horizontal plane occupied by said frame and a second generally horizontal plane parallel to and separate from said generally horizontal plane occupied by said frame, the first user operable hydraulic system drawing hydraulic power from a lift hydraulic reservoir supplying each of: a first lift hand pump and a second lift hand pump; and (e) a second user operable hydraulic system for tilting said cradle in an aft up or an aft down direction via extension or retraction of a hydraulic cylinder for adjusting an angle of said cradle in relation to said first and second planes generally parallel to said generally horizontal plane occupied by said frame, the second user operable hydraulic system drawing hydraulic power from a tilt hydraulic reservoir supplying each of: a first hand pump and a second hand pump, the second user operable hydraulic system separate from the first user operable hydraulic system, the second user operable hydraulic system shares no: hydraulic lines, hydraulic fluid, hydraulic cylinders, hydraulic pumps with the first user operable hydraulic system; (f) wherein each of a plurality of said apparatus is configured to be stacked along at least a generally vertical axis with another of the apparatus such that, when stacked, longitudinal axes of each of said stacked apparatus are generally parallel and each of the stacked apparatuses is configured to remain within a horizontal planar size boundary of 108 inches by 88 inches upon a shipping pallet.
