My 2 cents. I towed all my life. I have same truck as you. Unfortunately I towed with chevys with leaf springs and they were stable as can be. Always had sumo springs. Now I bought the ram.. I towed two trailers one 30 ft and one 24 ft. Florida disney long haul 10 hours and gatlinburg.
What I can say is youll be in 5th gear or 6th. Which is fine. leave in TH mode is all so TQ converter locks in. Truck ran a little hot in the mountains pulling hills. 260F oil temps....
Nex is the squirrly rear end on the ram. I put sumo springs yellow and a hellawig sway bar first link.. That tightened the rear up.
WD hitch is a must. Put as many washers in there as you can to tilt the head back and find the right link until the bars are close to level. Thats the best your going to do.
any TW you see advertised and 200-300 lbs to it. I have been through scales on all my trailers . Ya want 10% or better.
Any camper with a slide will be heavy period. especially what your looking at..
I have had all coachmans or pumas as they were the lightest. No sides.
You may pull it if ya go heavy but why white knuckle it.. Trust me on this. I towed a 30 ft up in the maggie valley with 4 people bed fully loaded with a 2004 - 4 speed 5.3L silverado long bed. 3rd gear or second pulling hills. 1st gear up the mountains doing 20 mph almost floored... Ugg I shouldn't tell any of yall.. Also lost brakes coming down. They faded out on me.. well enough of that story
Get a 2500 would be my best advice. Or look for a lighter TW trailer.. 7500 max GVW loaded or lighter
These are good options.. Not sure your family size though..
This is the best towing trailer I ever owned. I ordered with the complete wall to isolate the master with a door. My family toursed the whole east coast for 3 months in that thing... Lots of fun.
Best I owned

I also had an old clipper model. Like this. This was one of my first models back in 2005 a little different floor plan though. I pulled it with an old 96 s10 ZR2 - 1996 with a 4.3. Those 4.3 motors made all their TQ @ 2800 rpm. So I was right in the TQ band when towing highway @65 mph.. No issues.
