THANKS TO EVERYONE WHO HAS BEEN OF HELP! I bought a used truck with low miles with a great maint. record. I've posted in past about new vec.'s but think I've found an excellent newbee vec. And I got a good feel for good dealers for future truck purchuses . OK I bought a 2001 pete 330 with 195000 has class 8 frame 300hp cummins .I drove it back from ca. to mi. got about 11 mpg ,truck seems real tight ,handles like a dream.I should be starting with fed ex by months end . One problem is weight issue , for 3 years it has been with fed ex as D unit ,problem is 10 front ,21 rears and weights about 19000 empty . Short of "D" unit but has history of service as "D" . I hope this doesn't bite me in the butt. I've already priced a pusher and would still come in at an excellent price for unit. I guess my question is how much difference there really is between "D" and "c" ,also must add truck is set up for white gloves dry,lift gate dollies pallet jack etc. I GUESS WISH ME LUCK AND ANY ADVISE WOULD BE WELCOM. THANKS RANDY (BIG DOG)
