Just finished the wiring and hitch hook-up my trusty Bushtec Trailer to my 2017 RT. Question ... when towing my Bushtec should I use the "eco" mode or regular more? Would the "eco" mode still help my gas mileage? Would towing power be substantially better with the "eco mode off" and using regular mode. Or, does it make any difference? Maybe this address in the owners manual ... but I can't seem to find it? Thanks in advance for your input! HerbU
