In my experience full time 4WD systems feel unnecessarily heavy on simple road maneuvers. You can also kiss goodbye tight maneuvers. Add large wheels and you just compounded the heaviness. But yes bad weather and you feel like you have a tank. Also jeeps don't feel good if you ever plan on driving a bit faster. Even from the factory the speed limiter is lowered even further when you add larger wheels. I don't know how the 392 engine feels in a Jeep but the other engines feel slow when compared to my Acura MDX Hybrid (0-60 in 6 Seconds).
With all that said I have considered it to be able to take the roof and doors off. Pleasant experience.
