I needed a new truck that could tow my track car better then the 01 Tundra I had.  The Tundra has been in our family since new, dad bought it and I rode home with him the  day he picked it up.  I eventually got it many years later,  but it wasnt my primary vehicle.  It was only around for truck things and towing the car/open trailer.
I decided it was time to get something that tows better and can upgrade to a nicer, larger trailer.  My work commute went from 60 to 30 miles, so I decided Id be ok with daily driving a truck now, but gas milage was still a concern.  I also have 2 kids so needed something with room for the hole fam damily.  Started shopping around, Chevy was immediately out, my opinion they are hideous and cheap feeling.  I decided it was between a new '22 Tundra, F150 Lariant, or Ram Laramie.  Kicked around the idea of going 2500 but didnt want to live with an HD as a daily.  I liked the F150 for the towing ability of the 3.5 max tow.  The Tundra was a wild card, I didnt mind the look unlike most, but was wary of the first year of a new gen, even more so when EVERYTHING is new.  The unknown and the unattainability of the Tundra eventually removed that from contention.  The F150, I'm more of a Ford guy then anything, but they look so boring, and dont seem nearly as nice overall, inside as and out, as the Ram.  But it was a close 2nd.
But one of the biggest factors, outside of the fact I think the Ram is far more attractive looking inside and especially out, was the Gen3 EcoDiesel.  With my longer commute, and towing the car, I really liked what I was learning about the Gen 3.  Ultimately the EcoDiesel was the finally piece that tipped the scales towards the Ram.  The F150 had a few options I wish the Ram had, but not enough to out weigh everything else that the Ram excels in.
So I placed a order back in January, because if Im buying a new truck, Im getting it exactly how I want, and Ive had it for a few weeks now and love every second of it so far.  My F150 buddies give me a hard time cause its not as fast as their 3.5 ecoboosts, but who the hell really buys a truck because its fast.  I have two foxbody Mustangs for that, dont need to be ghost racing at every light in my truck.
