Hi,
Most 2500 series trucks do not make a good match for a fifth wheel. But I see that the GVWR is now up to 10,000 pounds, so they are getting better. If you had a gas engine, then the curb weight would be around 500 pounds less, and it might work while not exceeding the GVWR.
However with only 2,700 pounds of total cargo rating, and you and the wife and dog weights around say 400 - 500 pounds, the hitch will come in a 200 pound crate, then that only leaves say 2,000 pounds for hitch weight. That is not much when you are considering a 10,000 pound trailer with 20% on the hitch, or 2,000 pounds!
With a 3,000 pound hitch weight on a 200 pound hitch, and 500 pounds of passengers, you are looking at a dually truck, or at least a stout 3500 series truck that will be cutting the weight thing very close.
Stick to travel trailers until you are ready to upgrade the pickup to a dually. Or find a 3/4 ton suitable trailer. Titanium trailers by Glendale RV where balanced very well, so that the water tanks where located between the axles, and the hitch weight was fairly low, making them 3/4 ton towable!
You might want to look at other brand fifth wheels too!
Good luck!
Fred.
