Welcome to the forum! First, I would NOT recommend the VM Motori 3.0L EcoDiesel engine to anyone in a truck or towing application.* Reasons below. Second, to your question, there are two keys to happiness buying a 2019 Ram IMO:
1 - Know the typical problem areas by lurking on this site and reviewing the owner poll, and...
2 - Check for those problems thoroughly on your test drive,
before you drive the truck off the lot. DO NOT GET STARRY EYED ON THE TEST DRIVE, DO NOT ALLOW YOURSELF TO BE RUSHED BY THE DEALER OR YOUR OWN EAGERNESS.

Speaking from experience.
Do these things and you set yourself up to get a well built truck with none of the obvious bugs. Should problems occur after buying, find a
good service department and they will take care of you... perhaps not as quickly as some might need, but they will.
If you hang with all that you’ll have a solid chance of being happy.
(Oh and 3 - know what your payload needs are, and confirm the door sticker supports them. Don’t trust the marketing numbers.)
*Mine experienced catastrophic main bearing failure at 48k, many others have failed even earlier, FCA refuses to cover it with the Lifetime Warranty, FCA admitted the bearing failure problem but to date have not addressed it with any design champnges. Do what you want of course, I regret being tempted by the wonderful performance numbers.
