For this reason (Among many others), I am glad that I moved back to the South from SoCal...I imagine the 710 is a bear...I know it was in my Taco TRD 4x4...Unfortunately, I have no MIL...but my buddy Eric, who we call "Lunch Box," would do nicely for you guys...he's in the SD area. If you'd like, I can pimp him out for you
BTW the interstates in SC and GA are pretty smooth...some spots over bridges/overpasses can be hairy at the expansion joints, but NBD.
