The secret is that Dodge was offering some really big rebates across the board and those ended on June 30. I think, right now, they only major rebate they are offering is on the Big Horn trim level only. And I think it's only 15% off.
If you want a deal like what some of us got last month, you're going to have to wait until they start offering those big rebates again. Which will probably happen sometime between now and November. But, then you'll be stuck buying whatever leftover '19 you can find.
My '09 Ram 1500 was a dealer demo. I bought it with 6000 miles already on it. I just traded it in with 193K miles on it. If you can live with the 8.4" Uconnect, you should jump on that deal!
Be aware, I think your bumper to bumper warranty will not start when you buy it. It started whenever they put the truck in service as a demo. Also, you may or may not get the full amount of time on the free Sirius. That may also have started when they put the truck in service. All in all, a very small price to pay for the deal you described.
That said, the 12" was a requirement for me. I would not have bought my truck without it, even at $22K off. But, that's just me. Mine is exactly the same specs you're looking at, too - except mine has the 12" (which is awesome, BTW).
I would drop the sunroof. I've had a sunroof on my last 20-something years worth of trucks. I found that I pretty much NEVER use them. I was happy to find the truck I did with no sunroof. It's just one more thing that can leak and, for me, of no use.
I would definitely drop the sunroof before I dropped the 12" Uconnect.
Also, dealers will probably be getting a few more '19s in. The factory stopped taking orders for '19s, but that doesn't mean they have finished building out all the existing orders. But, waiting will definitely be a gamble.
