I’d been rolling for a few weeks without my soft-top back panels in. Rain or shine, I’d just wipe things down. I’d already removed the drain plug from the scissor jack compartment. Didn’t think much of it.
Turns out the back isn’t as water resistant as I’d imaged. Royal Oak Ford was kind enough to code-confirm, and point out (to them) the obvious: keep water out of the back cargo area.
If you (or anyone) really ever needs a code confirm, I can just hook up my laptop so no one needs to spend the $100 or whatever they charge usually. Or if you have Ford Pass I can look it up in PTS with your VIN.
