The penalty is 40%.
If MPG has meaning to you (apparently not) it would be obvious the EPA COMBINED is close to that number.
Researched :) BAWAWAWA
I'm a licensed professional engineer working for an automotive OEM, specifically working in powertrain group.
Want to try again and cite the exact source of this alleged 40% penalty claim?
Hook up a TT and find out. What’s the penalty? Steady-state difference, all else the same.
It’s common as a rule of thumb past 50-years.
Your “research” doesn’t extend very far.
Whether higher or lower, the difference will mainly be trailer design.
The noise in the numbers will be the mechanical condition. Which I’d never trust when brand new much less used.
AND
the validity of the hitch rigging.
If it’s much above forty, there are problems with those vehicles.
