i have same opinion as zukipilot. (zig). there are always going to be advantages for going SAS, and as zig mentioned, still being able to drive 90% of what others can with IFS, is one of the better things.
i dont know about how many people trailer their trail rigs to the trails, but i know that trailers are a hassle, to me anyway.
its not really how hardcore/over-board you want to go, it how capable you want your rig to be.
one of the main reasons why i got a vitara, was that everyone else has a sierra, and its easy to mod a sierra hardcore (for anyone with money). its more difficult for a vitara to reach the same level, BUT, it gives me a challenge, the challenge to build and develop the IFS to equal/better the Solids. i'd probably get bored after a while with a Sierra, as there is only so much you can do until you go beyond DD, and road drivable rig.
