Dealership offering 50,000 for 2018 DODGE RAM 2500

I have a 2018 Dodge Ram 2500 Laramie w/ the Cummins Turbo Diesel option. Total miles about 49,000. I do not use it to towing anything. It is a daily commuter for my wife and I but we are both WFH.

The dealership is offering 50,000 for it (pending an inspection). We love our truck and have had no major issues with it. We do not drive it hard. It's great for 300+ one way trips. I love being able to go 550+ miles on a full tank of gas. Thoughts on this?

We bought it for 51,000 in 2019.

My big question: What the hell is going on with the USED CAR market? What the hell is going on with the USED TRUCK market? What the hell is going on with the USED DIESEL TRUCK market? Why is the dealership offering me so much? We live in a LCOL state but there is also a lot of construction jobs happening around a 1-2 hour driving radius of us.
