## THE PROMPT (paste exactly; swap only <COLOUR>)

A clean photorealistic product render of THIS exact off-road box camping trailer, three-quarter front view, on a plain light neutral studio background with soft even lighting.

CONSTRUCTION: a steel frame clad in flat 4 mm aluminium-composite panel (bonded), forming a tall rectangular box. The front is a flat-fronted tapered prow — the box narrows in plan to a narrow flat vertical front face, full height. Body and nose are one continuous shell.

BODY COLOUR: <COLOUR>.

TRIM: all trim — edge strips, corner profiles and the single horizontal belt line — in bright shiny polished aluminium.

DOORS (exactly three, nothing else): (1) two flush barn doors on the REAR face — a wider left leaf and a narrower right leaf, off-centre split; (2) one full-height door on the RIGHT-HAND TAPERED PROW face. Every door has a black RV paddle handle and NO visible external hinges. The long side walls are completely blank — no doors, no panels.

RUNNING GEAR: chunky off-road wheels mounted on the OUTSIDE of the body, each with a 265 mm-wide fender; single axle set toward the rear; axle low, 100 mm below the body base. A-frame drawbar and hitch at the front.

ROOF: one flat 550 W solar panel lying flat on the roof.

Sharp, photorealistic, true proportions, no text, no extra doors or hatches beyond the three specified.
