How much squat can I expect?

I'm looking at a new 2020 Duramax 3500 4x4 (crew, standard box). The bed rails are 59" off the ground (3" taller than my 16 year old Dodge 3500). The bed is also 3" taller than my existing truck at 39".

With my trailer leveled, the bottom of my overhang is at 60" giving only 1 inch of clearance. In order to get the trailer to ride level and give 6" clearance to the bedrails, The truck would need to squat 5". Assuming the pin weight of my trailer is about 2000-2400lbs, is that a reasonable expectation? The payload of the Chevy truck is 4185 lbs. So, I'm guessing it may not squat all that much.

I never really paid attention to how much my Dodge squats under the weight of the trailer because the trailer leveled out pretty well (maybe just a tad nose down) and there was always sufficient rail clearance.

The axles are already flipped on the trailer. So, welding on frame sections as spacers would be my only option for raising the trailer. I'd like to avoid that if at all possible.
