Saying 4WD helps offroad is the understatement of the century.

I’ve extensively offroaded in vehicles that aren’t really built for going offroad - a Subaru Loyale 4x4 with/without a rear locker, a lifted Crown Vic, and a lifted P2 Volvo XC70. The crown vic was so much less capable than the stock Subaru Loyale or the Volvo, even with the trunk full of weight, due to it being RWD. It was all about speed and momentum to get up hills, whereas the Volvo can just crawl up stuff. The Subaru can’t crawl up stuff, as it’s a manual and doesn’t have the low range gearbox, but as long as you stay in the power band of 1st gear it’s unstoppable in places the crown vic would be totally spinning out. I always called the crown vic the hammer of offroading, since you kinda were just forced to send it up every steep hill.
