I would make two suggestions here:
1. Don't be in a hurry to sort out your interior. I know it is not fun driving around without a complete set up, but the last thing you want is to have to rip out everything again.
Give the seals time to dry, cure, and shrink into their positions....maybe a couple weeks. After that.....
2. Fill multiple buckets of water, climb up into the bed of your truck, and drench the crap out of the cab! I mean....make it rainnnn! If you have a water hose, that's even better. Just run the water over the rear window and antenna area at decent pressure for an extended period.
If you're still dry after that, then you can recarpet with confidence.
Again....don't be in a rush!
My unsolicited 2cents.
