I have to disagree.
I drove a 40th anniversary fzj80 from Buena Vista, CO to Golden, CO today at 70-80 mph until I hit the snow. It has an ARB front bumper, ARB drawers, Slee sliders and rear bumper, is running on 35s with 4.56 gears; and has an aux tank (both aux and main started full of fuel in BV), a Dobinson’s 4” lift with the MRA shocks, Tarrox calipers and rotors (brakes for days) and …a freshly rebuilt TRD supercharger.
I never really wanted for more power. It always accelerated nicely uphill, and quite a bit of the first half of that trip was over 9000’ ASL.
I paid… less than half what that white 80 went for.
Drove a 92 around BV to get coffee. It was also on 35s. Now that truck was underpowered.
