Buying a 2020 Silverado 2500

Well it’s time to for a new truck. i came across a 2020 Silverado 2500 duramax. it has just about 105k miles for 39k. is this a good deal? so I’m looking for advice on the reliability on that year model. any common issues? i drive about 10-15k miles a year. sometimes up to 20k. it will be my daily plus work truck hauling skids from job sites to picking up materials.
