I’m going to chime in at the risk of being flamed....
I own a Brute with a 392 hemi, and have for a number of years. It has 40s and 1 tons and goes camping all the time with the flippac on the back.
The power is outstanding, and totally excessive for overlanding, however so are the tires and axles. The mpg is not good, in fact this is my biggest issue with the vehicle. I will be installing a aux tank some day for range anxiety.
This vehicle does what “I” (and my family) want, It is not for everyone. It is my personal vehicle and built to take on stupid trails solo, and not worry about breaking something and yet, still go camping. If I had the ability to travel globally I would not own this vehicle and honestly would prefer to own a 3.0 crd in this truck, regardless. (I like diesel tho)
My point with all of this is...... to each their own. Jeep sees a market of “mall crawlers” or otherwise they can sell the 392 to, so good on them. I am happy with my 392 but it is not for everyone or even every trip. I have one truck outside work and I want to to do everything well. “The master of all, but expert at none” approach, and the 392 helps in this, even with its shortfalls.
Cheers
