I know HDPP is available on 6.5 Supercrew but not with max payload, something closer to 2800lbs (which is still the best on a half ton). Also had a Ford dude say the 3k plus payloads are on only the reg cab work truck. Ford states: "*Max payload on F-150 XL Regular Cab, 8’ box, 5.0L V8 4x2, Heavy-Duty Payload Package".
I have read that HDPP is a unicorn and really hard to find. Might be easier to find a 3/4 ton with that capability and not that much bigger or more expensive truck. Also the main attraction for me to the F150 is the ecoboost 3.5 but they don't do that with the HDPP only the V8. We have rented a few in the transit and LOVE that engine.
Are you in Canada? Your profile says SLC, the same state as I am in. For the US, you can get an F150, 3.5 Eco, 4WD, HDPP (there is no “max payload pkg”), max tow in the Supercrew 6.5’ bed.
Just build one up on the Ford site if you’re still confused.
