Youve got a good DD. With stock tires and stuff you should have decent gas mileage. You say 5 spd, so Im not sure what gears, but I think if it came with 31's (stock) then you have 4.10 gears and if smaller tires, than smaller gears. The V6 thirdmember in the rear axle will have a 4 pinion carrier, so your better on strength there. The 8" is a stout axle, comparable to a 44. Even the IFS is strong as long as you dont squeeze all the lift you can through the torsion bars. The 3.0 is gutless compared to the 4.0 we have, but it still has enough mmph to get its light weight through most anything. The problems with it are the headgasket stated earlier, and the exhaust manifold design is retarded at best...the pass. side manifold has a crossover pipe that goes behind the motor over to the driverside manifold and dumps into it almost at a forward angle. All that exhaust dumps out the driverside manifold exit into the exhaust. Other than that, check CV boots on the front axles, make sure the hubs are good (AISIN hubs are the bomb for real), check for rust, smell the oil if you can for coolant (headgasket), and dont let the miles scare you.
