You will need mirrors that are wide enough, either add on, or possibly full replacement. A firm called KSource is the OEM for many or most car manufacturers and they also sell aftermarket, might be a place to start looking if needed.
As far as engines, the 2019 came with 4.3L or 6.0L Gas or 2.8L Diesel. I'll bet it is the 6.0 and that is a very good engine for towing, and should easily handle the weight in the size range you are looking at. Note that the LWB models have the same GVWR as the short wheelbase models, so they do not have as high a payload.
If it does not have a receiver hitch, get it equipped with a good one rated for the max tow rating of the vehicle.
