Well your problem is going to be finding a light enough 5th wheel.
You have a GVWR of 6700#
Curb weight of 5292#.......leaving you with 1408# of carrying capacity
You have a RAWR of 3900#
Curb weight of 2997#....leaving you with only 903# of capacity on rear axle
Now subtract weight of you, passengers, all stuff in cab (backpacks, bags, stuff under seat, in door pockets etc.) and the weight of 5vr hitch from that 1408# (actually from the rear axle capacity of 903#)
Example.......400# for people/stuff and 200# for hitch----600# from 1408# only leaves 808# for 5vr pin weight. (OR 303# before reaching RAWR)
Typical 5vr pin weight is roughly 20% of trailers weight
20% (808#) would be a trailer roughly weighing 4000# fully loaded to go camping. (OR only 1500# based on RAWR)
150/1500 trucks are better suited to tow 'bumper pull' trailers as you can 'tow' a bigger/heavier trailer with WD hitch vs 'carrying' a 5th wheel.
You will exceed RAWR long before you reach 'carrying capacity' with a 5th wheel.
And with that short bed you will need a slider hitch for a 5th wheel which are even heavier
Tow rating for your truck is 5258#
Max tongue weight with Class III (bumper ball) is 500# but with a Class IV (receiver hitch) is 1200#.
Tongue weight roughly 15% of trailer.......so a 5000# trailer max.
