I realize that this thread is pretty old but thought it best to keep the Project M discussion here.
I'm awaiting delivery of my M in July. Until then, I'm prepping for the major issue that arises in discussions about these campers, dust intrusion. My truck has a spray-in bed liner so that's taken care of some of the leaks in the seams of the bed. I plan to use liquid Flex Seal to mitigate what's left.

Sealing around the tailgate will be the major challenge, I think. For that I plan to use one of the commercial weatherstrip products made for this purpose. Can anyone suggest a product that they've successfully used for this purpose? There are several on the market.
We need to leave room for a crate for a large dog, so our buildup of the interior will have to work around that. I plan on putting down some L track to secure the crate and then cover the floor with a bed mat. That should provide some comfort and some insulation as well.

I'll cut some slits in the mat where the fasteners for the L track will come through to secure the crate.
Looking for some experienced opinions on this plan.
TIA.
