Good looking truck Marty.
The wifes same white '16 1500 4wd crew cab short bed truck (5' 8") with 5.3 6 speed 3.42 gears replaced her older same configuration '06 model.
Nite and day different.
The '16 is so much quieter on the road or just idling. Her '16 5.3 with 355hp/383 torque has a heck of lot more torque in the lower rpms than her old '06 5.3 engine. We prefer driving it over a 2010 Impala on short or long trips.
AS your equipment I can load my 7240 lb blue tractor on my 10k car hauler (bumper pull) to get any hitch load needed.
Barney talked me into a Husky Centerline TS WD hitch with 1200 lb bars for this size/high CG load. This tractor has 14/9-28" rear tires and sits tall on the trailer. Pulling nothing but GN trailers I was surprised how it cut trailer over steer. Only problem was pogo sticking even with new Bilsteins.
A call to etrailer for their input on stiffening up the rear springs with this load. They suggested the black Sumo springs. Cured the pogo sticking and a easy install.
