Re: Manufacturer websites not current?
Yep, and the information you get from the social media sites is often filtered, sometimes severely, to suit whomever is running it. I look at some of the Facebook sites occasionally, and they often are "ours are best" mutual worship with no useful information, and heavily populated by the hyper socials.
If you happen to live a long ways from the dealers for the brands you want to research and there are not shows in your area, the websites are about it and should be up to date and complete. On many sites the specifications section is getting smaller and less detailed as time goes on.
