So you have a friend-fold sleeper you don't like and a table & chairs in the same TT that you wish was a booth dinette. It sounds like you maybe jumped the gun on the new TT purchase. I hope you got it at a VERY reduced price (30+ % off "MSRP" or better).
If the TT wasn't what you wanted then why buy? It obviously was not all you wanted because you have already posted about two modifications and it's not even a week old.
I know you all just had your STOLEN TT returned, but it seems odd to have went out and purchased the new one if it wasn't what you wanted.
