Just spent the past few months researching, test driving, and trying to decide on a truck myself and ended up with a 2019 Tacoma TRD Off-Road. Picked it up this last Sunday actually.
I test drove this truck, as well as the new 2019 Ram 1500 and a Silverado 1500 for a full-size alternative and finally decided on the Tacoma. I was happy with the room the DBL Cab Long bed gave me and although the Ram is a beautiful new truck, it didn't stick with me like the Tacoma did. I did plenty of comparisons like power, size, equipment, and capacities to both the bigger full-size trucks and at the end of the day, my day to day commute and needs couldn't justify a full-size. It also doesn't hurt when your father has a 2500HD for all the heavy work.
Of course this is only a personal opinion/story but my advice would be to take your time and look for something you'll be happy with overall, not just something your going to compromise on because of one power train option or one equipment group.
