The Weber grill, as I understand it from previous posts, is an electric grill, so I'm not sure that it would be functional for most camping. The X Lite series, as far as I know, doesn't have a 50 amp availability, so adding an electric grill will further impact the usability of the rest of the electrical system.
Deleting the grill is probably a "win" for customers, LED lights are definitely a bright spot in the package (pun intended).
I haven't heard about a change in package names, but it wouldn't surprise me if Cougar tried to separate the X Lite series from the Cougar series by changing up some of the features and names of packages. Getting them to be too "much alike" would muddy the sales and ordering. Sort of, "Why pay for a Cougar High Country if you can buy the same features in an X Lite for $5000 less... "Beginners" seldom look at frames, tires, hidden features, rather just look at the names of packages and RV brands. A Cougar is a Cougar.... or is it ????
