2015 SRW Ram 3500 Cummins (First year review)

I pretty much only use my 2015 3500 for towing, and now have a little over 8000 miles on it. Gas mileage averages right around 10mpg while towing, only a couple tanks running without the trailer but hit almost 20mpg at 80 to 85 mph. DEF usage much higher than others reporting, around 12 gallons to go 8k miles. Lots of whistles and bells, even dims highbeams for me, decides when wipers need to be intermittent or full blast. GPS maps could use updates, and voice controls are worthless for the nav stuff, work fairly well with phone, text messages etc. Rear air suspension is really nice, ASIN transmission mixed bag as it tends to hunt to much. TransForce tires actually get good traction towing in snow, rain, and do good on dirt roads if they are dry and don't have a lot fo gravel. They are wearing rather quickly though. IBC is sad to the point of being dangerous. Overall though, nice truck, towing beast, acceptable on paved roads empty, a little sad on the dirt roads which is just the way it is with 1 tons.
