Are 2 Wheel Drive Rigs any good?

Maybe look into getting a locker tl you can go a lot of places with a locked up rear end. And if you know you're more likely going to be the one stuck invested to some good recovery here a good kinetic rope shackles, make sure you have good strong tow points
 
is swapping yours to 4x4 out of the question? not sure on the Isuzu platform but some rigs the 2wd and 4wd are built on the same platform so you can just part out a 4x4 and swap everything over .
