Looking for a new heavy duty work truck.

Currently driving a 2008 GMC 2500hd with 236k miles.

I do a lot of driving, towing, and offroading.

I would like it to be a diesel but willing to look at the gasoline models.

New or used but currently only looked at used because a new 2500 is $60k+

Needs to be a 2500 or larger and I love idea of getting a dually if it would fit my price range.

Not a fan of dodge but know nothing about the Cummins. (every single one at our company has had major problems and without a truck you don't work nearly as much.)

As for pricing the company gives me $1,250 a month torwards the truck and maintenance. Anything left over is mine to keep.
