in short, what's the easiest way to say that this truck can pull this FW?
Post the specs on the trailer or give a link to the manufacturer's website with model number.
There is a near continuous discussion on "what can I tow" or "will my truck tow this" or "what truck do I need to pull this" discussion in tow vehicles forum.
Trailer pin is listed dry and will increase. Truck payload capacity is reduced by options, passengers and cargo. It is a bit of fuzzy math until you put it on a scale and by then you own it. Welcome to the fun ;)
