Crew Cab 1500 X31 HEIGHT Clearance in Underground garage.

Hey guys, I’m about to purchase a 2025 Sierra 1500 X 31 crew cab with the 3.0 L diesel engine and I’m seriously concerned about this thing fitting in my underground parking garage. The garage has a ramp heading down to the door and I’m worried that the roof may scrape towards the back of the cab as it goes up or down the ramp. The clearance is 82.68 inches or 2.1 m Internet tells me that the actual height of the truck is 76.8 inches tall I’m worried that that 5 inch difference might not be enough if the back of the truck is higher than the front on the ramp

I attached some photos for reference .
