We just got back from a 2 week 5k mile trip to New England towing a 37' Montana 5th wheel with 3 slides. The truck performed flawlesssly. The worst towing mileage was 11. 2 and the high was 13. 1. I took the combo across the CAT scales and weighed 21,760lbs. Front= 5480, Rear=6480 and the trailer was 9800lbs. I ran the trip with a brand new fueling module from QUADZILLA which has three settings. They are stock, 75HP and 150HP. I ran at 75HP the entire time. The high temp as recorded on the SPA was 1220. I was really impressed by the chip. The transmission ran a little hotter than I though it would. It is a 6speed with the coolers on the sides. I filled it with new Redline MTL before leaving. I recorded a high of 218 degrees with a ambient of around 98. The rearend never got above 180 with a Mag Hytec and Amsoil in it. I will need a clutch. The stock unit will slip slightly on the 75HP setting if the RPMS are low and the drivers is stupid and slips at will on the 150HP setting. We sure had a great time except for all of the the alternative lifestyle explaining we had to do after visiting Provincetown, Ma. What's up with that???... . CJ
