Dealer said Rams website has false advertising???

Long story short, I’m trying to finalize a purchase of a CPO truck and the warranty that’s advertised on Rams certified pre owned website is showing the CPOV warranty changed to 5 years/100k max care coverage from the 3 month maxcare 7/100k powertrain. I’ve reached out to Ram directly and have been told that the 3 month is correct and have also been told that the 5 year maxcare was correct. The dealer told me today that the rams website is incorrect and it’s “false advertising” (their words not mine). I’m wanting to move forward with the purchase however I am really uneasy without knowing exactly what the warranty even is if there is one at this point. Really frustrating.
