I was the first Moderator of this forum, and did the job for several years. What AZ Kid is saying is true.
This is the Class B forum, and size of the RV is irrelevant when it comes to what is a Class B.
There is nothing wrong with discussing/comparing different sizes of RVs, but specific posts that are about a Class C (B+) need to be made in the Class C forum, or they will be moved there.
I own a 19' TT that is smaller than most B's but Im happy to post in the TT forum, even though most of the TT there are much larger. Just like posting about a small C in the C forum.
