Thanks again for the help,
The truck is a 2016 F-250 4X4 with a 6.7L power stroke diesel platinum edition with tow package and ready for 5th wheel hitch to be bolted in. Its rated for 14,000 lbs conventional and 15,100 lbsgooseneck.
The trailer is 10,600 dry and with the tanks if full adds another 1400, I'd will be close to the limits of weight for the truck if using the 20% (12,080 lbs). Is this too close? Will the truck be a dog going down the road?
No, you'll be just fine. The GVWR on your truck is artificially low for reasons unrelated to capability, so being close or frankly even a fair amount over your payload rating is no big deal provided you're comfortable with it - your truck certainly will be. I'd pay more attention to your axle rating which I assume is in the 6500 range.
Edit - my comment is assuming your GVWR is 10k lbs.
