Hello,
I have owned 2 Monaco Sigs with slides, and 2 Vantare's without, It was a mindset at first to go to the non slide. You need to decide what is important and how you are going to use your coach, and then finding the layout that works for you.

Our current Vantare has a very OPEN plan that works well for us. it can be seen at http://blog.northernjetsales.com/?page_id=651

The thing we dislike about most slide coaches is that when the slides are in and traveling there is restricted access to some places you need access to. Some of the slides take up much of the aisle space making it difficult to move from front to rear of the coach.

I almost made the mistake of purchasing a 4 slide Travel Supreme until i had the dealer bring all 4 slides in and then try to walk through the coach. It was not an easy task, and imagine trying to get to the potty with the coach moving down the highway at 70mph.

Almost all with a rear slide require climbing over the bed with the slide in.

Slides are nice when you are in a park, and if you are living in the coach. if you mainly use the coach for travel, then my vote is for a non-slide.
