Firebox Trailer Side View Blueprint - Cooler & Propane Layout (CAD Sketch)

This document is a screenshot of a CAD/drawing-program layout (likely Visio or similar, shown on a grid with a ruler scaled in inches from 0 to about 130) depicting a side-view plan of a trailer or firebox rig. A scale callout reads '5 in.' near the ruler. The drawing shows a large rectangle at the left (roughly 0-72 on the ruler) with a smaller rectangle in front of it (roughly 15-45) sitting above a large circle, which appears to represent a wheel/tire centered around the 47-inch mark. To the right of the main body are two square boxes each labeled 'Large cooler side' (spanning roughly 60-90 and 90-115 on the ruler) resting on a horizontal platform, and at the far right a rounded-top cylinder labeled 'Propane' (roughly 118-130) standing on a lower shelf or tongue element. The file is titled 'Firebox side.JPG' and belongs to an album that also contains 'Rear.jpg' and 'Top.JPG', suggesting it is the side elevation of a multi-view blueprint for a homemade smoker/firebox trailer build. No vehicle-specific text, part numbers, fuse data, or dates appear anywhere in the drawing.
