I'm just poking fun at people that spend thousands putting 4x4 type accessories on a 2wd truck.
Fwiw, 4x4 has its uses on full size trucks, but serious off-roading isn't one of them. It's more like not getting stuck quite so easily on a particularly rough patch of road or slick spot or when it is a bit snowy or icy. There is a reason you almost never see them on more serious off-road trails: high centering, weight making ground pressure and inertia too high, and crap turn radius.
They can power through mud on huge tires or on a straight line trail up a steeper section, but hit some rock, something requiring lots of off-camber driving, soft ground, soft sand, deep snow, deep ruts, and especially switchbacks, and they're at a serious disadvantage. It's still useful to have it when you need it, despite that.
Basically it's me saying brodozers can mud, and climb straight line, and not much more.
