I have outgrown the rock-crawling phase and at the end of the day with the right gear, driver skill and knowledge of your rig you can get you anywhere a jeep will go to begin with.
Not a chance. The full size truck simply will not fit where the Jeep will. It's longer, wider, heavier, doesn't turn as sharp, it isn't balanced as well, ... they're completely different vehicles.
A skilled driver may get a full size truck through the same terrain that challenges an inexperienced driver in a Jeep, but if you take two equally skilled drivers, who are equally experienced in their vehicles, the Jeep will get to a whole lot more places than the full size truck.
The question is - do you want to go to the places that the Jeep will get to but the full size won't? Five years ago, I asked myself that question - the answer was "no". I sold the Rubicon & bought the 3/4 ton Dodge & not long after added a FWC. It was a good move. Our travel habits were changing (less technical terrain & more hanging out at cool spots) & the truck/camper was a better fit. Given those travel habits, there are a ton of advantages to the truck & camper (range, capacity, "live in" vs "live around", durability, on-road comfort, fuel economy, the list goes on), No one knows what the future will bring, but for now, I'm happy with giving up the technical terrain in exchange for some creature comforts.
Maybe you will be too - just don't lie to yourself, it won't go to all the same places as a Jeep.
