This is really cool! Do you have any pics of the three sections laid out in the X by chance? Does this let you lay flat onto the the folded down front seat?Made some progress on my sleeping platform and will probably finish sometime this weekend.
Its about 10" in height and split into 3 sections. Rear section is about 32x34 houses 2 drawers. Both sliders are 100lb full extension so the grill will slide out with plenty of room to spare. the other drawer will house supplies and recovery gear.
There is a middle section about 5x43 that was made because the rear section would be too big as a 2 piece to stack in the rear, and the front section is a hallowed out and about 32x43.
I needed the middle section because it is built to be stacked upon each other in the rear and allowing the rear seats to be used and expands to three sections when sleeping with storage access from the passenger doors into the front section compartment.
as we use the grill more, ill find out what works best for materials and setup. I may put down some thin tile under the grill section so oil and grease are not an issue. Im sure ill learn some lessons along the way.
I've been considering building a sleeping platform for my X, but I hate to give up the easy access to the under floor storage in the back. I'm also thinking about roof top tents but that's a whole other level of investment.
For now I've just been going with a double air mattress in the back, which is easy and comfy enough for a night or two.
