I will agree with most of what has been posted.......that is too much trailer for the listed truck.
I have almost the same setup, but with a Super Cab, 6 1/2' bed, tow rating at 9300 lbs. The tow rating may be OK ( if the trailer is not loaded to the maximum), but the hitch is not rated for that heavy of a trailer, nor will the GVWR or GCWR probably be with limits.
With me towing a 5500 lb. trailer with a 700 lb tongue weight, by the time I load up the missus and the dog, along with some gear in the bed of the truck, I am near the GVWR of my truck. Pulling a 8000 lb camper, along with passengers (bunk beds = kids, plus the missus ??) and cargo in the bed will probably put you over the GCWR, as well as the GVWR.
Unless the truck is the Crew Cab with the 6 1'2 bed (vs. the standard 5 1/2' bed), the wheelbase is 145". IMHO, that is bit short for a 1/2 ton truck pulling a 33' trailer.
The projected tongue weight of 1100-1200 lbs. is going to severely stretch the limits of a receiver hitch built for to carry 990 lbs. with weight distributing.
That is too much trailer for that truck in so many ways.
