• (e) an upper pivot element mounted on said frame:
• (f) an upper pivot engaging element mounted on said hopper for engaging said upper pivot element when said hopper is pivoted about said lower pivot element to said first predetermined angled position and, upon engagement between said upper pivot engaging element and said upper pivot, for pivoting said hopper about said upper pivot element to a second dumping angled position at an angle greater than said first predetermined angle;
• and
• (g) lifting cylinders mounted between the sides of said frame and the sides of said hopper for pivoting said hopper between a horizontally held position and said first and second angled positions for dumping materials from an end or said hopper.

• (e) an upper pivot element mounted on said frame;
• (f) an upper pivot engaging element mounted on said hopper for engaging said upper pivot element when said hopper is pivoted about said lower pivot element to said first predetermined angled position and, upon engagement between said upper pivot engaging element and said upper pivot, for pivoting said hopper about said upper pivot element to a second dumping angled position at an angle greater than said first predetermined angle;
• and
• (g) lifting cylinders mounted between the sides of said frame and the sides of said hopper for pivoting said hopper between a horizontally held position and said first and second angled positions for dumping materials from an end of said hopper.

A dual use dumping vehicle having belly-dumping and improved end-dumping capabilities, comprising:

• (a) a frame with a front and with a rear end with a plurality of rear wheels, including rearmost wheels mounted to said rear end of said frame for rolling transport thereof;
• (b) a hopper for transporting materials, said hopper supported in said frame for two stages of pivoting of said hopper with respect to said frame;
• (c) a lower pivot attached to said frame for pivotably supporting said hopper during a first of said two stages of pivoting;
• (d) an upper pivot attached to said frame for pivotably supporting said hopper during a second of said two stages of pivoting, during which second of said two stages of pivoting, materials in said hopper are dumped at said rear end of said frame, said upper pivot positioned on said frame forward of said rearmost wheels of said plurality of wheels;
• and
• (e) an angled dumping chute attached to said rear end of said frame for guiding materials dumped from said hopper past said rearmost wheels.

A dual use materials transport vehicle having belly-dumping and capability capabilities for dumping materials from an end, comprising:

• (a) a frame with an end;
• (b) a hopper, having an inside surface and pivotably mounted in said frame for dumping materials along said inside surface and out of said hopper at said end of said frame;
• (c) a rear chute, having a central area and mounted on said end of said frame at an angle for directing dumped materials from said hopper downward at said end of said frame;
• and
• (d) opposed deflectors mounted on and along said inside surface for directing at least some of the dumped materials toward said central area of said chute so that smooth dumping of materials is facilitated.

A method of constructing a dual use materials transport vehicle having improved capabilities comprising the steps of:

• forming a frame with left and right box beam rails, a front beam and at least one rear beam with an open space defined therebetween;
• connecting a plurality of rear wheels to said frame;
• providing a hopper with belly dumping capabilities and pivotably attaching said hopper within said opening of said frame;
• and
• (d) attaching left and right hydraulic cylinders between said left and right box beam rails, respectively, and said hopper for pivotably actuating said hopper between a transport position and an end dumping position.

A method of constructing a dual use materials transport vehicle having improved capabilities comprising the steps of:
