ND ,don't get your hopes up thinking you'll have a good selection of2021 and now 2022 current Chevrlet body style,slim pickens nation wide,further prices on new trucks,most dealers today full sticker (due to lack of availability) price less any cash from the factory,$1000 in my area,one dealer near my small town here in minn,was advertising they're 2021 suburban,sale price was $20k over sticker price,none around,so be mindful and if possible slow your purchase process,
Further the "new generation" 2022 1500 silverado startup is january 2022,big changes,hopefully good changes...
you won't find a glut of 2021 GM trucks anywhere,iifin you check out the rice burner (nissan) slam the truck door,sounds like a tin can unlike ford/GM trucks with side impact enforcement,not sure about dodge? price wise if your dodge dealer has trucks dodge most often is the cheapest,they don't sell well nationally so bigger retail incentives.
Goodluck!
Word on Gm trucks things will get back to normal by 2023/inventory & prices
