F150 or F250

Welcome to the forum !

It is not rocket science, nor that confusing either. Just need to see
the whole systems picture (how it works and interplays on each rating,
as each rating is only a part of the whole system) and gather some
'real' data. That means to have actual weights, not published or guesstimates

Here is a quote of mine from another thread that applies. The original
thread is also in the below hot link "Lots to learn"

Notice that, that OP was using the brochure or published weights. Like
'dry' weights. Others use 'curb' and 'MTWR' (max tow weight rating). All
of them use the 'stripper' model. Meaning no options and most all
vehicles today are ordered optioned (AC, automatic, 4x4, upgraded
everything)

Lots to learn

First decide if you believe in the OEM ratings or not

If not, then do whatever and note that you have taken the liability
and the OEM's are off the hook

If yes, then read up and this quote/diagram should help you 'see' the
whole picture of the ratings system(s). Really easy and simple math
once you understand both how the system works and some of the terms
which are to be followed or are meaningless

Then figure out which advisor believes in the ratings or not to base
your decision using their advice

That your wheels won't instantly fall off if over loaded...just sooner
and that your PERFORMANCE will be reduced

Above quote from this thread: Trailer Weight Calculations & Load Estimator Utility...five pages of discussion

The OEMs use 'stripper' models (curb or dry) to derive the ratings
The only way to know for sure where you are in reference to those
ratings is to actually go out and weigh the whole setup axle by axle

So many folks have a hard time understanding and/or accepting that
the OEMs do this and in reality the OEMs have no choice because of
the buyers who only look at the brochure numbers/ratings. To decide
their purchase based on the 'King of the Hill' comparison numbers

No one knows you and how you pack. From nothing to taking the kitchen
sink plus the dog... :B

So you can do the simple math using the GVWR's (the rated maximum of
both the TV and the trailer). Some will argue never will reach GVWR
to some who will advise it's okay to exceed because they designed in
'safety factor'....which is true...but how much and will you reach that?

Good luck!
