Well would you rather get into a gunfight with a .22lr or a ar10 .308 because thats basically the same question, will a 22lr kill? yes with good shot placement and enough ammo, will .308 kill better?yes with alot less ammo. That is pretty much the difference between a stock 4x4 and a fully modified 4x4. Will a stock 4x4 be able to offroad? Yes with the right line and plenty of patience but a fully modified one will do it better with alot less trouble.
This is funny but kinda true. If you watch a lot of TV and movies, and that's how you want to shoot, you will be emptying your AK47 into all the cars, walls and industrial equipment while everyone is hiding behind them. Me? If there's only 2 guns allowed in thatfight, and my choices are that I get to spray indiscriminately with the AK or think a moment and take a good shot with the 22LR, I'll take that 22LR and land one through an ear while the guy with the AK reloads. Or bird dog him.
Translating that back to 4x4...I ride in 2wd at almost all times. I really only ever "shift" (it's a knob now, unfortunately) into 4wd when I know there will be ice on the roads, or other slippery, tricky conditions. Then I shift out.
If i take the lower bumper chin strap off this truck, i bet i can get most of where i want to go with it in 2wd and the highway Geolandars currently on it. Add the stock 4x4, my G80 Eaton auto blocker rear (stock) and i bet i get 80 to 90% where i want to go, or even more
