I do not like the basic f150forum, the aesthetic is poor, and the site is too popular, which means it is flooded with both good responses and terrible, useless ones. People often respond about your question about a newer f150 by telling you what their junked out old 2002 f150 is like. Pointless.
If you're buying a new f150, head to f150gen14.com, it is by far the best.
If you buy an ecoboost f150 and want solid advice or have technical questions, f150ecoboost.net is also terrific. But a lot smaller member count, so sometimes a little slow. The responses you get there are on point, though.
I tried nearly all of them (too many choices) when shopping and then buying my 2019. Definitely enjoying researching, planning and carrying out my mods. Starting to get close to how I want it.
