Ok, so I pretty much read most of this and don't post much but I have to chime in here.
I have a Work and Play 30WRS and I would like to say that my wife and I preferred the sofa slide over the dinette of the 30WR. We do have a fold out dinette in the garage as well as another fold out sofa and it was the perfect setup for us. There is more floor space and feels much larger than the 30WR unit.
That being said, our unit has definitely not been without issues of any of the RV's currently being manufactured. In the first 6 months, we are now on the third A/C unit, the bed completely came apart, the doors on the pass-thru storage leaked, the pull down screen for the cargo door fell off and many other issues.
I dealt locally and my dealer has been great and Forest River has been great so far. Not sure what we will run into this season and I hope they will continue to take care of the issues. That will remain to be seen.
Now, this all being said, it appears that you are looking for a bigger garage than what we have on this one. My advice on anything that you buy would be to deal locally and not have to travel to get issues fixed. I fixed most of the problems myself, but certain things like the A/C units need to be fixed by the dealer and you certainly don't want to have to travel a long distance to have that taken care of.
