You ever wheeled an IFS? I have, and I mean over rocks and crawling. It's a different style, but fully possible. I took my stock Geo Tracker places tat people with much more built vehicles were afraid to go. In the rocks, will my XJ outdo it? Oh heck yeah, but it still can't match my stock Trackers performance in the wash, over whoops, etc. There's more to wheeling than rock crawling.
Look up the H3 Adventure package. 4:1 t-case, 33" tires, front and rear electric lockers, skid plates all around, and you get a nicer more comfortable daily ride along with it. Yeah, still IFS, but as stated before, IFS can be wheeled and taken over rocks while handling gofast better than a solid axle ever could.
