Online forums are still a great place to get information and to discuss topics you are researching or that you enjoy.
I tend to do a lot of research before making any large or long term purchase. Vehicles and accessories that go with that fit in this category. Here are some of the forums I follow.
Jayco Campers Forum
Ford Focus Forum
Ford F150 Forum
Honda Pilot Forum
Reddit tends to have a subreddit for anything you are researching too, but some subreddits are not too friendly to newbies 🙁
Do you still use forums for anything? What are some of your favorite?
