Confusing and Overwhelming... But there really isn't any nice way to present the volume of information.
There are about 8 main topic areas, then under each of those are numerous subtopic areas.
I go to the above page, scroll down and look at Forest River Tech Talk and Motorhomes.
Under each of those I find more specific topics. I usually look at about 12-15 of the sub forum topic ares that I've learned may apply to me.
The problem is, many items that are discussed could have been placed in several (many) different sub forums.
i.e. someone is having a problem with a broken plumbing fixture on their hot water heater. They may put this in the Forrester Motor home forum, However, this particular subject could apply to almost every motorhome or trailer in this forum.
There is a lot of very valuable experience and information here, but it does take time to weed through it to find stuff that applies to you.
