Buddy runs one on his 2015 LML and tows a 32ft 5er. No issues and truck runs well but your not going to pick up any mileage running one. Only way to really improve mileage on emissions equipped diesels is to delete the emissions via tuning. Would take a LOT of years to pay for itself in fuel savings though. Probably not an option for you living in CA.
Why install a tuner to tow a 32’ 5er? We tow a 32’ 13,000#+ 5er with a 2016 Ram 3500 CTD, Aisin, 3.73’s and it does great without a tuner.
Because you can... Dont think he installed it specifically for towing. We all run our trucks empty 90% of the time.
I have the same truck but a 2012 LML that is stock. His truck is noticeably quicker than mine unloaded but gets a little worse mileage than me. We tow similar size 5erS around 13-14K GVWR
