    I was wondering if anybody has driven both a base 2022+ SR vs a SR5 or higher trim that has more hp. Can you feel much of a difference under normal driving or is it only at high rpm’s it makes a little more power? From what I’ve read the only difference is the ECU tuning, the actual physical engine is the same. Please chime in if you know more about the differences.

    Thanks!

    Torque is also limited. Since torque peaks on the SR5 at 2400 RPM, I would think that might be noticeable in normal driving, and especially towing.

    If you look at the specs, the SR torque is 405 at 2000 rpm and the SR5 is 479 at 2400 RPM. So it sounds like the SR and SR5 might have the same torque curve up to 2000 rpm and then the SR gets capped while the SR5 continues to build.

    That said, the SR power/torque numbers are pretty close to a 2011-2014 F150 Ecoboost. The 400 torque is actually a touch more than the Ecoboost would be making at 2000 rpm. I have a 2014 Ecoboost and tow a 5500 lb travel trailer around UT, MT, ID, WY, and CO and can tell you it is a very strong setup.

    So I would say that the SR would still be a very stout powertrain even if its not as strong as the SR5. I dont think you would ever be disappointed with it.

    Just planning to tow a small travel trailer that weighs around 4k fully loaded and a dirt bike and some gear (500 lbs). Wondering how it would tow. My old 2018 4 cylinder taco (2.7) pulled it but the power was lacking. Struggled to go over 60mph at 4k rpm towing.

    it will be fine, engine power isnt the most important thing for towing necessarily anyways. control and stopping the load is more important.

    Assuming you have enough to get it going that is, which the SR has plenty of torque, in fact if mass-hole is right a few posts up, the 5.7 peaks at 3400 and the SR has more torque at 2,000 rpm than the 5.7 has at peak 3,400

    It’s still winter here so I haven’t had a chance to try the truck and trailer package. Thanks for the feedback. I’ll try to make some YouTube videos of it.

    You will weep with joy the first time you pull it. Youll probably be cruising at 70 mph turning 1800 rpm like its nothing.
