Assume exact same model, year, options, GVWR, diff ratio, etc, etc
Then it depends on:
- Driving style
- Maintenance schedule and how religious they followed it
- Materials used
- What they towed in reference to the TV 'true' ratings
- Terrain
On that maintenance, I mean stuff like flushing the automatic ATF (for
my Sub, that is 16 quarts) every other year. Power steering fluid
every other year. Flushing the whole brake system every front brake
pad change. Greasing all zerks at etc engine oil change, which I change
on a 3K-5K schedule and use Mobil 1 synthetic and PureOne filter. Flush
the diff fluid when I do the tranny fluid (dino for the tranny and
synthetic for the diff). Flush the radiator every other year with
American Green...all 15 quarts of it
I even take a spray can of primer/finish paint whenever underneath
to spot anything that looks off.
Read folks advising to over load with the 'sure you can', 'have been
doing so for decades/thousands of miles with no issues', etc
Those I would not touch if I knew they overloaded...as the OP aludes
to with his comment of ".... I'm thinking the sturdier 3/4 t would
be a better older TV..."
Some advise to use XYZ oil and filter because they change their oil
every 20,000 miles. I'd not touch that one
Some advise you can tow heavy running 75 MPH. I'd not touch that one
There are some two year old TV's that I'd not touch because they were
driven over loaded and very fast. They are 'old' to me. Then compare
that to the exact same TV that was towing a hybrid. Which one has
had the design margins consumed? Which one still has lots of design
margin?
and a big ETC...
