Ok . I dare to be different... I like the last one (tan ) the best. As far as the set up .
I lived in Hawaii ( it's been a few years) Mil litairy...
But as i remember , the closest freeway is about 4000 miles away.
You will want a regeared rig (For the hills) you will want a descent tire (for the sand). If I remember correctly 70 miles an hour isn't to important in Hawaii so a stock ish engine should be great. A hard top would be nice though. Or at least a lock box in the back...I have found that If you have a wheeler , you will go off road , Trust me , you will need the lift. Or at the very least enjoy having it...Especially on the islands..
Test drive ,Test drive ,Test drive...
Find a stock ish one , and drive it ...Then look at modified Zukes. Drive and compair them. Find out what you like and dis like, and then make your decision...And don't be in a hurry. You live on an island . Where you gonna go....Boxcar.... Good luck..
