So apparently when the sunroof is open to the rear, water will leak in and soak the rear compartment.
Got my new (to me) vinyl tarp that is thicker than those dumb blue or green chap tarps, that don't last long, and are either too short or way too long. The vinyl tarp I got is a repurposed tarp from a billboard and ended up being the perfect length and width for my D1. I chose to use the back side (Black) as I figured the neighbors wouldn't like the advertising on the other side. A 21+ Marijuana ad for a dispensary.

The kid and I had a good laugh. at least the Land Rover is over 21 so I guess it is legal age...
