It's my pot and I'll stir it if I want to. If you're not careful, I'll stir your's as well!

What makes you think that you need a gear change?

I agree, depending on your gearing it is likely fine.
I run 35 on two trucks with stock 3.5 gearing.
I run 37s on two trucks with stock 4.1 gearing.

I would not even consider 4.56 gearing on a low idling Cummins diesel truck, unless I was building a rock crawler or running 44 inch or bigger tires.,

My truck has 3.73 gearing on 315 tires with zero problems, even when towing my 12,000 pound RV in the mountains.

It feels like some posters ask a question and people take the time to reply with answers and them the OP never checks back….

Makes me less likely to invest my time trying to answer questions.

Agreed. Been seeing more and more of this over the last few years. Unfortunately this now seems to be the norm, particularly with the new posters. Between this, the bots answering many years old posts and apparently no more moderators, this once outstanding site has gone down drastically. How sad!
