Hi
Mounted a tailgate table on my 2 door 2012 Sahara.
Called Trailgater from Outback Adventure Products and Bought it from Rebel Offroad and have very high quality and is expensive.
No drilling and mounts in some minutes. Fits with subwoofer
I bought the one with Bamboo cuttingbord.
When folded up there are small room for 4 plates, food, spicies, cutlery etc. I will also use my stove on it.
This will take a small Cargo space, about 1.8" and my Waeco 25 liters fridge/frezeer still fits when the backseat is up.
