Ditto the other guys opinion, it's an excellent combination. My truck is
identical to yours, with the 3.92 LSD. My folks have the same drivetrain
in their '99 Durango as you describe and tow a 2500# trailer accross the
states on trips. The Durango pulls it like there's nothing back
there. Gotta drop to 3rd gear in the mountains, otherwise it pulls great
and gets good mileage at 65 mph.
I can't recall exactly but I think the avg. RPM at highway speed is around
2400-2600 @ 65mph, 1400 @ 45 mph with TC locked-up (I get to commute in it
lately...). Seems to average 15-17 MPG on highway trips @ 65 mph. Not too
low, definitely more power! 4.11 would be too low with 31x10.50x15 tires.
Good luck!
