This plan builds a 26" X 48" meatwagon with removable wood box and optional fuel rack. The plan is adaptable for various widths & lengths however, I have found the 26" x 48" or 30" x 60" to be the most popular.  Meatwagon pictured is a 30" X 60".

Sample paragraph

Cut three pieces of 1/1/2 X 1/8" angle and weld to the tongue & frame in a rectangle (using the frame front as the fourth side).  The size is determined by the size and number of fuel containers you desire to carry.  I use a rectangle of approx. 23"W X 11"D (a 23"  & two 10 ¾" pieces) which holds three 1 ½ gal. jugs.  Bolt a slightly smaller piece of 3/8" plywood inside the rack for a floor and weld a small ring or tab (I use a half piece of chain link) to each side as a tie-down point.  If you plan to use a fuel rack, insure the tongue is long enough so your ATV tires will clear the rack in a turn.
