Just ordered at 05 shortbox DRW 4x4 with a 6.0 I am looking at installing the Edge system with ATS propane injection. Has anyone done this combo and if so what are the pros and cons. I tow a 15500 boat, am I going to need ATS trans and converter upgrade? Is my EGT going to be my limiting factor in towing? and should I be looking at water injection to keep my temp down on long hills?
