The size of the Engine, Cab, and bed determine the towing capacity of a truck. You have listed none of these so it is impossible to tell you it's rating. I suggest you go to the web page listed below and click on "Tow Rating". Locate your truck to see what it can tow.
The conventional towing capacity for a 1983 Ford F250 with a straight six is between 12,000 and 14,000 pounds. The fifth wheel towing capacity is up to 16,000 pounds.
The 2009 Ford F250 6.4 liter diesel pickup truck has a listed towing capacity of 8500 pounds. The manufacturer recommends that you do not exceed the towing capacity.

The towing capacity of a 2003 Ford F-250 varies depending on the engine and configuration. Generally, it ranges from approximately 10,000 to 12,500 pounds for conventional towing, with the maximum capacity reaching around 15,000 pounds for fifth-wheel towing. Always consult the owner's manual or manufacturer's specifications for precise figures based on your specific vehicle configuration.

The different sizes refer to the engine and towing capacity. The larger sizes generally effect the fuel economy as well. You can find the specifications at http://www.fordf150.net/specs/05sd_specs.pdf
The most important thing to do is to find out the weight of the 5th wheeler and determine if your truck has that towing capacity. A 1/2 ton truck should be able to handle it. A F250 will also be able to handle it.

Open the driver's side door and look at the manufacturer's plate. Look for the GVWR which is your gross vehicle rating. That is your towing capcity combined with the weight of the vehicle itself.
Maximum payload is 6120 lb (2780 kg). Maximum towing is 24500 lb (11100 kg). The better the towing package, the better your results!
