Thinking about downsizing my truck. Currently have a 2016 Chevy 2500 diesel. I basically only use it to tow a 25' travel trailer that is 6K loaded and to go to Costco every other month. The towing trips are mostly flat. Once a year I tow up in the mountains.
Now, I'm looking at 2019 Chevy 1/2 tons. The trim level I'd like to get would have a 5.3 and a 3.42 rear with an 8 speed. I could step up to the 6.2 10 speed, but the required trim level would add about 10K to the cost.
I know neither of these would compare to the diesel in towing, but would the 5.3 get the job done well enough?
