Looks great. I have the same tent. I was hoping to find a rack that sits the RTT below the roof line... and still works with a tonneau. Looks like the only options are the embark tonneau, which takes up too much bed space with the canister. I think I'm SOL.
I noticed the exact same thing. I was really surprised Ford would put it into production like that, assuming it's as-designed. I created a thread here last week:

That's a good point. I need to stop by the dealer next week (driver's heated seat isn't working, and paint contamination.) In the meantime, I'll fold the rear seat up/down and see if I hear anything obvious.
I definitely get the piped-in sound, it's more of a low-mid rumble through the speakers. My RS does the same thing. But this 2nd sound is like a rear window cracks open under throttle. Sounds like a boost leak, but from the rear floor.
Has anybody else noticed this? Stomp on the pedal, and it sounds like the turbo is sitting in the back seat. I was a little surprised by this. It's coming up through the floor or something. Lariat crew cab.
