Yeah that double motor one wont fit in the front a a patrol but would work great in the back.
My understanding of winch out heat of the drum is that when pulling in the brake disengages and allows the drum to spin, the brake locks on when you stop pulling. When you winch out the brake remains engaged and you drive through the brake with the winch motor creating internal heat in the drum centre immediately. Avoid winching out. Even spooling out using the motor is not ideal.
The himount has the external brake which is a winner.
