I know these manufacturers keep raising these numbers like there's nothing to it but at some point reality will kick in. Physics WILL come into play at some point no matter what they put on paper.

Aside from a 1/2 ton pulling a 5th wheel which I've seen done but.... a 5'10" bed for a fifth wheel? The bed on my new truck is 6'5" and I was VERY worried about buying a 5th wheel (committed today) due to that. I was told by 2 service shop managers that it could/possibly would be an issue in certain circumstances. That's 6'5".

Sorry I don't know about what will fit the new truck but I certainly would worry about buying such a short truck to put a 5th wheel (read high/leverage) over such a light truck....and, max tow capacity is just "paper talk" so be careful.
