Only problem with that year of truck (or any up to 2010) is the limited payload for trucks with the diesel.
If its a 4WD, Crew Cab long box you could be looking at less than 2100# of payload.
Check the yellow label on the driver's door pillar to see what it says "Occupants and cargo not to exceed xxxxpounds".
That weight needs to handle all occupants in the truck, including the driver, a full tank of fuel, the weight of a hitch plus the loaded pin weight of a fiver or tongue weight of a TT.
You will find that to be the limiting factor.
