Sun Room Atrium Specific Class A Model Information

[cloudbaseracer]

Hello,

I am new to the forum and looking to get our first RV. I believe I am mostly interested in a diesel pusher but not sure if I want a full 41' coach. The Friendship G8 with the Atrium/Sun room slide is what my wife and I have fallen in love with but I am curious.......

What does the 8411 in the model mean?

How do I determine what other models - Crescendo, Tourmaster, Sun Voyager, Independence, etc. have this same sun room?

Is there a database that some kind GS Owner has compiled that would give me this information?

Are there any 36' - 38' models that have the sun room that are also diesel?

We feel we need the diesel as we will be doing quite a lot of mountain travel pulling a full size SUV but the 41' size worries me that we will be limited in places we can park.

Thanks!!
James
