Its bent vertical supports leave room around the tongue and propane equipment.

Check A-frame fit and clearance before mounting
The CC-255 mounts to many A-frame trailers, but fit must be confirmed for your trailer. The manufacturer's instructions place the lower mounting pockets approximately 2–3 inches forward of the trailer body and the tray approximately 1–2 inches from its front wall. The tray width and the bent support location influence access to propane tanks and the tow vehicle's turning clearance.
Check the A-frame for interference from wiring, battery boxes, propane connections, equalizer brackets and other installed equipment before positioning or drilling the supports. Follow the manufacturer instructions for final assembly and securing the bolts. Use at least two people to position the heavy tray.
