The Caddy I upscaled from to a new 6.1 recently, had a grilled top section of the bulkhead. This was great as it let light and some ventilation into the cargo area, ideal for my work companion, Drake a big old black labrador. The new wagon has a solid bulkhead so putting him the back is not an option. Is such a retro fit available please? Thanks in advance for any tips or steers. Cheers
