u/Helpful-Dot-8586

Went to take delivery of this truck today and noticed its thumping at idle. Pretty audible in person. Dealer took it into service and said they’ll let me know, if they can’t diag they said they can’t honor the sale. Any input? It’s hard to hear in video but if you listen closely you’ll hear it. I’ve read that some people have similar experiences coming from the intake, this is most noticeable on the lower end, from driver front wheel well. And can be heard in the truck

This is primarily a question about the price and the value over all.

I’m supposed to be picking up this truck tomorrow. I’m super hesitant but I feel like it’s not a horrible deal. For my area (NY)

2020 2500 High Country with the 6.6 Duramax.
100k miles
1 owner
Seems fully loaded up, I can’t pull original sticker on it so I’m not sure.
It’s pretty mint inside and out for the mileage and year

I can get it for $51,500 out the door. That’s after tax, doc fees, etc. I’m not familiar with the market on these trucks. Im coming from a 2023 RST Silverado. Looking to buy this truck to tow my sxs and toys more comfortably. I’d appreciate input.
