I don't know what your price range is, but if you're buying something in the People's Republic of NY that is 6+ years old, check it over really well for rust. Mash and release the parking brake a few times to see if it holds/releases and then crawl underneath to check for P-brake cable sag. If it's sagging, the p-brake hardware is seized and a dealer fix for this is like $1400 these days. It's a very common issue for rust belt Ram 1500s, but you can mitigate it. Lots of threads on this site on it. You've got a nice clean shot of the p-brake cable in your 3rd picture above for reference.
I know you say you want the hemi growl, but you say you're not towing or hauling anything. Have you driven a pentastar powered Ram 1500 w/ the 8spd? They're awesome too. I owned a 2017 quad cab 4x4 with the pentastar V6. The only reason I still don't have it is I wanted to upgrade to a crew cab and I couldn't find a used CC w/ the V6 at the time and got a deal on my 2019 classic hemi 4x4 @ $26K w/ 15K miles on it back in 2020. I get it though. You might be one of those 'V6 ain't a real truck' guys. The reason I brought up the V6 is you might find a better deal on a 2013+ V6, quad cab, 4x4 model.
