I have a 2016 DRV RSSB3 , GCW of 19K, so you’re is heavier. I have truck in my dig and am full time. Towing now between WV and TX. Truck tows very well on steep mountainous curvy roads and on flat land, I have to admit, it’s like it’s not back there, ( NEVER thought I’d say that). I like the rear air assist and the medium duty Aisin transmission. I have the 4.10 gearing which gives you the highest GCWR. I’ve read on here at times a lot of people think the 3.73 is the best of both worlds, but am hearing now a lot are staying with the 3.42gearing. Guess it’s your choice. I’m in some steep secondary rads at times when in VA, TN, WV and NC. I’ve had 4.10 gearing in Ram trucks since 2010 and never an issue. It’s what I tow with and I wanted the 4.10. Just preference. Others have theirs. I would get the puck system where you can drop a hitch in.. just makes it nicer, as well as the cargo camera.. nice for hitching up the 5er. Hope this helped
