You’re fine.
Presuming this trailer is tandem axle 24’ ish based on weight, it’s about all the Durango wants for physical size, but the exact same chassis, everything but the engine is rated higher with bigger engine.
The engine is the limiting factor here, to combat the sail/anchor hooked to it.
Like I said, won’t win races, but there’s plenty of vehicles with a lot less overall power/gearing hauling around 5klb trailers.
Your presumed inexperience towing would be better served with a vehicle that “tows it like it isn’t there”, but that isn’t what you have. It’s hard to explain to newbies, especially among the litany of “you’re overweight” responses, but it’s fine. WDH and working trailer brakes will be necessary and let er rip.
Or to put it another way, same drivetrain in a Ram 1500 is ALSO rated to tow it.
New Durango’s are super capable, like most new vehicles. Bulletproof trans and great brakes.
