Anyone towing with traction bars cal tracs or other ?

What are you worried about?
You should have zero problems with them towing or not.

Not worried just want to know if anyone is doing it and how they like or dislike it.

Towing a 5th wheel and using Tuff Country 10997 bars on a 05 Dmax. It does help in loose gravel or soft dirt. I have had one break though and in the process of getting a replacement. The Tuff Country may not be up to the forces the Dmax can generate.
