Whats up fellas, so heres the deal. Im wanting to build an overland rig but i can decide on an xj or wj i like the simplicity and price for pretty much everything for the xj but im concerned the 4.0 will lack the power needed to haul my family and all the gear im going to be putting in and on it on interstates to get to places and up trails which is one reason im leaning towards the wj with the 4.7 v8 but ive been told the 4.0 xj gets better mileage because its lighter and it also seems a little more "rugged". Would love some opinions and feedback thanks guys!
