The 2019 Ram feature is actually a sponsored add by Ram, not an article by PU.com.
They do have an article dated 2/25/2020 about the 2020 Tundra TRD Pro and it appears that they had been getting articles out a rate of about one a week before that but nothing that excited me. I would say that they are alive but just barely. In fact, checking on it was probably the first time I looked at the site this year. I used to check it at least daily.
Sadly, I think that some of the most loyal users killed it by getting too stupid and vile in the comments section. PU.com eventually had to turn off comments and the entire site seemed to lose its vitality. It also seemed to be that comments here got a little nastier shortly after that. I hope that those problem users didn't come here with their bad attitudes. This could be a case study in why we need to keep things friendly here.
