HI FRANK C, I CAN'T COMMENT ON PANTHER, BUT AS FAR AS TST GOES, I HAVE BEEN THERE JUST OVER 8MO, AND I HAVE 3 D UNITS THERE. I'M HAPPY SO FAR, MY TRUCKS AVE BETWEEN 1700-2200 MILES A WEEK, AND ALL THREE ARE SOLO DRIVERS. DISPATCH IS FAIR, AND PAY SETTELMENTS ARE ON TIME AND ALMOST ALWAYS ACCURATE. HOPE THIS HELPS YA OUT, GOOD LUCK:+
