I will COMPLETELY dissagree on the FJ80, the newer ones with the lockers, are far too large for most trails. I have seen old school ones on trails, but never a newer one on anything but easy trails. Thats also not a fair comparison since the new ones have no lockers and are useless, you have to compare new to new, not old to new or what could be added as mods.

As far as a rock buggy as a trail rig? Sure, if you have another 30K for a Titan tow rig, 3,000 for a trailer, dont do expeditions or interconnecting trails, dont do long easy trails, have a 50K+ budget for the rig, dont want to drive cross country to a trail head, dont want to take your family.....Rock buggies are a vastly different wheeling style.
