1500 Trim/Year model question

Ive loved Ram 1500's ever since they updated the appearance and interior, its simply the best in my opinion. My question is, now that im looking at used trucks (Fucking pricing is insane for new and used) is there actually any difference between the 2019 and 2023 or 22 or 21 years when it comes to the interior of say a used Limited or Laramie from 2019 to the years following? I know ram hasnt updated anything really and minus the addon features you can put on each trim is there any baseline difference that RAM built into the trucks production based on the year it was made?

​

also how much negotiating room do you think there is on used truck pricing?
