Hey Ben,
This isn't IRV2, never will be and wasn't meant to be. But consider this. You own a WBGO Journey 36DL. and when you look at suggestions, problems questions here you can zero on on the content that relates DIRECTLY to you.
Sure on IRV2 you could see a post about someone with an issue with their Pop-up Trailer hitch or some other TT specific item in the right column sidebar. And those threads have their place. But here you'll know you're conversing with other WBGO owners. And, in the Class A forum with other WBGO Class A Owners just like you.
It's OK to have a couple of forum options. And you'll ultimately choose which best suits your needs. But if you ask me, a winnie owner, the chance to talk to other similar WBGO owners is a solid plus, not a step backward.
Before I purchased my 2017 Adventurer 37F this past July I had a 2015 Forest River Forester Class C. Great RV. And, I visited the Social Knowledge Forest River Forum regularly and made friends there. It was a great resource and real help to me.
But when I bought my WBGO there wasn't any similar forum to visit. Nowhere to talk to other WBGO owners with Class A's like mine. So, I ended up at IRV2 where there was only ONE FORUM for EVERYTHING Winnebago. Now that was a step back.
No one can decide for you. You'll vote with your feet. If you like it here, you'll stay and if you don't you'll go back to IRV2. I call that a Win-Win.
