Sent my Master Carpenter-in-Residence (MCIR) on a long haul over the weekend. He has a 3500 Ram with the "legendary" 6.4L HEMI. For 3 years, he has boasted and quarreled with First Husband about his power and strength, purporting to have equal if not greater towing capacity. Well, enter Crybaby, stage left: as he approached the Appalachian Mountains, apparently the HEMI squeels as it winds out with high RPMs up or downhill, towing a mere 7000 lbs. For my mainstream 2011 Cummins with the NOHO (no high output) 68POS, this would be like wearing a hat! But wait for it, this is after I just paid $8,500 for a new ATS Billet transmission rebuild! What the heck? Today, MCIR finally admits that there is no way in hell he can see his pathetic HEMI towing 13,000 lbs. It seems you have to have the thing revved to 1000 MPH to access the alleged power and towing capacity--not realistic on I81.
