Hey Guys.
Good news and bad news here. Drove 2+hrs to a dealership here in WI... to look at the 2 Rams mentioned in my OP. Overall, both were very nice pre-owned vehicles. I won't ramble on specifics, but both were nice. The 2020 had a 'USB error' issue, that once I looked it up on the way home... makes me kind of happy I didn't buy that one. Onto the 2021... I liked the HK system, but honestly, to my 50 year-old ears, I didn't hear much difference between it and the Alpine in the 2020. I had to stream through Spotify to be able to actually compare what I listened to in the other truck and besides the Alpine being a bit more 'bass heavy', both were very similar. The HK was very nice, don't get me wrong... perhaps I expected more. Long story short, the dealership was/is a 'best price' dealership, which I wasn't told... so that sucked to hear that after driving 2+hrs to get there.
So, I have some thinking to do tonight... and some reading up on this 'USB error' thing, which sounds like it's a temperature related issue from what I read on the way back. However, oddly enough... it was 55* here in WI, USB ports should be operating fine in that temperature. If anyone has any quick links to share here to save me some searching, please feel free to share. I know it's off-topic a tad, but thought I'd ask. They said they'd need to get a new USB hub approved and would have to install that... and they should, because this is a CPO vehicle and that should've been discovered. I think...
Anyways, just wanted to share my thoughts.
