Agree...go out and weigh it at a weigh station
No chart or formula will ever get it...as how does it know how much 'that' driver
weighs, their passengers weigh, their pets weight, the 'stuff' they loaded into
and onto the TV
Ditto the trailer...there is no chart in the world that knows what any given trailer
weighs.
Ranges is about as good any chart can be without actually weighing
Shopping for either or both...yes the charts are good to provide an approximation
of what it 'might' weigh...but it will NOT tell you what it will weigh
A good example of a 'chart' weight range...
I'm 6'0 tall. 'Husky' or 'Athletic and toned'. 67 years old
I actually weigh in at around 180 lbs, butt naked. 'Around' because I
don't weigh the same day to day, nor with whick clothes/shoes/etc
worn that day...which can add 10-15 lbs or more
The best insurance actuary charts will only give a 'range' for my weight...
