What are your future plans? You upgraded from a 2018 to a slightly larger 2019 trailer - that's fast. Any chance that might happen again? (Do you suffer from 2-footitis like most of us here?)
I towed our X19H with a Chevy Traverse for several years before buying a full size PU. The Durango has similar towing specs. The Chev towed the smaller (slightly - very similar weight specs) 19 well, but I traded early because the towing was causing some expensive maintenance issues with the Chevy.
Check the payload capacity on the Durango, and consider carefully how you will use it. Payload is fairly generous on most 3-row SUV's (after all they should be able to hold 7-8 adult passengers). However, remember that the max tow rating on the SUV is with the driver ONLY in the vehicle. As you add two (growing) children to the mix and a dog, you are quickly eating into the payload and reducing your towing capability. If you plan to keep the SUV for 10 years then those kids will be 14 and 16 (much heavier) and the trailer will probably be bigger too.
Buying an appropriately sized PU will future proof your setup. I find the back seat in my Nissan CC to be much larger than in the Chevy - kids really like it, and there is more versatility in the bed arrangement. I do still have to keep a close eye on the payload (always the limiting factor when towing RVs), but my towing capacity is about 4,000# higher now, so I have a lot more options.
If you decide to go for the Armada, I can vouch for a bulletproof drivetrain. It is the same engine/tranny (completely US made) as the Titan, and it tows very well.
