re: F150. 2.7 v6 turbo or 5.0 v8?

2019 3.5 v6 here. I am getting about 19 mph combined use according to the computer. It feels like I’m driving on air. Response and pick up is outstanding. Test drive the same truck with the 2.7 and I just liked the response better with the 3.5 and do some light towing from time to time and wanted that extra assurance of performance with the bigger 3.5 in that regard
