It will pull fine, the only time I ever thought I could use more power was going through the sawtooth mountains, the combination of high elevations and long 11% grades meant I could 'only' go 50 in the small 55mph straight. For all of the other 27k miles across 30 something states I've been more than pleased with the performance so unless you live in the foothills of the Rockies or Sierra's and regularly have to pull over high passes it's great for a trailer the size the OP is looking at. If that's your situation then go with an Ecoboost or the Chevy/GMC diesel.
