Going to chime in w/ my thoughts. DRW w/ that much weight. 16K dry and probly 20K max for the RW and IMO, it's too much for any SRW truck despite the mfr's stating it can tow "X". We had a '15 F350 SRW SB,4x4,CC, 6.7 and thought that would be our last truck. Then 2 years later we upgraded the RV and that put us over on pretty much everything even tho truck was rated at 11,500. 1st year, no problem as we stayed "local" (NE area). 2nd year vaykay plans were taking us to FL in Aug and knowing I was over on things .....especially the tires, gut feeling wouldn't go away. So ended up trading the SRW in for a '17 F350 DRW,CC,4x4. Towing wise, freaking great. Everyday cruiser when needed, okay, but can live w/it. Wintertime, IMO, STINKS ! Wife said she feels more comfy driving the DRW while towing the RV than she did the SRW w/ either trailer we had and she only tows the RV when she's the relief driver for a spell. Will admit, she's very GOOD at it to. Play it safe and go DRW.
