I am planning on buying a 3500 to tow my 2017 Redwood 5er. Since I am retired and don’t drive much on a daily basis would I be better off with the 6.4 with 4.10 gears? My 5er weighs in the neighborhood of 16000 lbs. and most of my towing consists of annual trip to Florida. I have been told that it’s hard on the diesels to just drive short trips around town. Also if anyone has this setup and tows something similar to mine I would like to hear how your truck handles it. From a newby thanks for any replies.
