It does depend on how you use your coach !! If you use it for partying like going to and from games with groups of people no slides would be fine... however if you are a travelling family there's nothing like puting the slides out when you get where you are going... we went from a 2005 4 slide Navigator to a '98 double slide H3-45... we didn't notice much difference because the H3-45 feels much roomier inside than the XL... we didn't feel like we lost much... there's nothing like a Prevost for drive and ride and the H is awesome... also we love the Vantare conversion.
It's all a personal preference... just get to know what you are buying before you buy it. Also would not buy a coach without OTR... (over the road air)....especially an H... also good when it comes to selling !!
Good luck.
