This for you OP
My truck is a 2017 F350 SRW CCSB. I have a B&W RVK3300 and a RDS 50gal Auxiliary fuel tank. Full of fuel and hitch in.
F-4780, R-3720, G-8500
Trailer has Washer and Dryer (no gen). Now with truck and trailer fully loaded and ready to camp.
F-5000, R-7300, G-22940
That is a pin of 3800lb and total trailer weigh of 14440lb
The Truck pulls and handles the trailer very well no problem lots of power and stopping good also.
You just need to know that the numbers in the book just are not real life numbers.
