2020 Ram 1500 classic 6 in lift and 37’s what’s the best gear ratio to run with this setup??

It's a Jeep thing. Glad people from the cult of Jeep chimed in.
Driving on the highway at 3000 rpms is not my idea of a good time. It is way too much like riding in the old trucks.
Unless you haul it on a trailer, you have to get there first.
