America First!
I have recently installed a 6.2L military humvee engine in my XJ and get close to 26mpg. I paid a whopping $80 from a military auction. I might go with a duramax later but with the budget I had this is working great with the economy already. On the trail the 165HP and 300ft lbs are not much different then the stock 4.0 gasser but a turbo would be real nice on the highway and for towing. all in all if it is economy and trail work a 6.2l or 6.5l can be found pretty cheap as long as you do your homework on setup and checking out the block first.
