We rented a Toyota Tundra from Avis last week to move my kid to college.
I don’t know about whether we were allowed to tow (and we didn’t) but it had a 2x2” frame mounted hitch receiver and a 4 pin flat wire hookup.
They had a bunch of them and all were equipped the same way.
If I were in a pinch, I’d probably bootleg it. But I would try to find a legitimate way to do this first.
“They had a bunch of them and all were equipped the same way.”
Hertz, Enterprise Budget and others allow towing with their trucks. I bet Avis does also.
