2021 GMC Sierra 3500 review
Has a really Big feel to it. I currently use mine to pull gooseneck trailer. I haven't had a load yet that I couldn't pull. The downsides to this truck is to me I feel it could get better fuel mileage. Also I had trouble with #4 injector...dealership replaced it. Now my AC doesn't work all the time. Although it sounds like it's blowing it isn't.

Snell Motors review
Our salesman was wonderful, not pushy, great listener to my needs, desires, and communicated clearly each vehicles values. The negotiation was painless, and I am confident I made a good decision in vehicle I chose. I would recommend this dealership and salesman, Ryan to anyone.
