We are pulling a 42 ft Solitude with a 2022 3500 HO dually. I don't really notice the RV back there when driving. (I am very aware of the length in tight corners.) We scale out at about 17,600 (18,000 GVWR) and our pin weight is right at 3,500 lb - almost exactly 20%. It's a short bed so we have a 250# Pullrite slider. We carry a couple boxes of DEF, 15 gallons of spare diesel, some tools (50#), 310 lbs of people and cat, and maybe 100# of miscellaneous stuff in the truck. It adds up pretty fast if you include everything in the truck that wasn't there when you picked it up from the dealer. That puts us at around 4,300#, over the payload of any 3500 4WD MegaCab SRW Rams. I originally wanted a SRW but like a safety margin so went with a DRW and am glad I did. The tow is "rock solid". A DRW gives several advantages. More payload, more rubber on the road for resisting side to side slippage, some safety margin with a rear blowout or flat, and, probably most importantly, a wider stance for tipover prevention. After watching a number of Youtube videos of fifth wheel tipovers, it was a no brainer for us.
