Own a 2020 with a 5.7. Great truck, great engine. Love the sound of it. Last summer rented and drove 2k miles a Grand Wagoneer L with the HO hurricane. Fantastic motor - power, torque delivery, smooth, refine, very efficient (600 mile cruising range with four people, three dogs and luggage). Anyone here blasting the hurricane probably hasn’t driven a vehicle powered by one. You know what saying is appropriate for the internet - there is an *** for every seat.
If ordering a truck today, I would get the SO hurricane. Plenty of power - most importantly a flat torque curve - more than the V8, and a bit more efficient. To hedge the risk inherent to a new engine, I would use one of the forum vendors to get an 8/85 extended warranty at a good price. If the motor goes 85k and is problem free, or at least normal in terms of reliability, then my experience is you are relatively safe to keep the truck as a car or truck that is reliable for 8 years won’t generally all of a sudden “explode” with serious issues if it has been maintained and driven normally.
For our summer trip this year, we will rent again and I will try to get a Wagoneer or Grand Wagoneer as compared to the Suburban or Expedition XLagain because I absolutely love the powertrain in the Wagoneer.
