I like 4Runners but extra cabs have advantages I also like. You can't beat the wheelbase of an extra cab for stability but that extra wb can also get in the way. The shorter wb on a 4Runner has its advantages to get into tighter spots without damage so both are good for different reasons. When you add duals the extra cab has the advantage since even with having to shorten the rear drive shaft you will still have no issues with travel and angles due to a short ds. That being said the shorter ds doesn't seem to bother a short wb 4Runner either. What it will come down to is what you want a pickup or an SUV with a removable top.
