I think you are overreacting a bit...OK...A LOT! Forums will always have people with problems posting problems more than you may have folks posting how much they love their truck. On my second RAM and had no issues with either. Loving my 2021 and would buy another and recommend to friends and family. Be very cautious about what you read. EVERY vehicle made will have issues or lemons. Enjoy your truck and don't get caught up in all the crap you read on forums. If you read all of the forums for GM, FORD, RAM, NISSAN, etc...you would never buy any of them
If you think a warranty will give you added peace of mind, and plan to keep it more than 3/36, then buy the warranty and call it a day.
ENJOY YOUR TRUCK and don't let other peoples experiences taint what is a great product!!!
