I've worked at a marina for 30 years and I tow up to 47' boats on a regular basis - not with my T4R if course. For my own towing, I had F-150's for years but got tired of stuff breaking. So, in 2014 I bought a Tacoma TRD Sport 4x4 which comes with the towing package. It did a reasonable job of towing my boat, so when it came time for something new, I stayed in the family and bought a 2021 SR5 Premium.
To say that the T4R tows the exact same boat better than the Tacoma would be an understatement. It's more comfortable, turns tighter, gets better mileage and generally just feels much more comfortable with the boat behind it.
What am I towing? I have a 1992 Progression 22 with a new four stroke (4.6 liter) Mercury Racing 250R on the transom. The trailer is a 1992 EZ Loader single axle with surge brakes. Although I've never weighed the whole thing, based on published weights for the boat and motor, I'd guess the whole thing comes in somewhere between 3,500 and 4,000 pounds.
