I'm looking for a new truck at the moment. Currently have a 05 v10 crew cab short bed with 4.10's. I tow a tool trailer 6-8k lbs weekly and also have a dump and equipment trailer that are 14 GVWR. I'm nervous that the 6.2 isn't going to do as well as my v10 and that I don't drive enough to justify the 6.7. I'm 15k miles a year probably. I do run boxes and racks on my truck so it is pretty heavy all the time. 8-8.5k. I average 9 in town with my v10 and 6-7 towing heavy and plowing snow. How do you guys think that the 6.2 and 6.7 would compare? Thanks
