Some OEM's make a distinction between tag a long style trailers and fifth wheels. It really just depends on how the OEM was feeling that year.
How much fiver you can tow is directly impacted by how much pin weight you can carry.
If you have a F150 with 1,800 lbs of payload but want to pull a fifth wheel with 3,000 lbs of pin weight then you have a problem. The F150 may have a 12,000 lb tow rating but a 10,000 lb fiver will put you way over that 1,800 lb limit.
Some will say that you are only a few hundred lbs over so no big deal, while you may get away with that on a tag-a-long trailer a fiver may put significantly more weight on the truck than just a few hundred lbs over payload. Putting 3,000 lbs (easy on a fiver) of pin weight on a truck like the F150 will put you 1200 lbs over in my example and that's before you add the weight of the hitch, family, firewood, etc.
So, you can run the calculations using the above method on just about any truck. Look at the payload sticker on the drivers door jamb and then look st the pin weight of the trailer. Is there payload left over for everything else after you subtract the pin weight?
This is why you typically see HD trucks and dullies (not all use a dually) pulling fivers.
