I've owned both types & currently own one without again. If you need the room then you need the room. That's for you to decide.
Did I have some issues with the 5ver I had with multi slides, yes. None of them were catastrophic, more like pains in the rear end.
We have a Class C now & decided no slide out version. Two reasons we wanted that right now. Desired less stuff to potentially break in the event we want to loan the thing to one of our kids to use &/or ever decided to rent it out. The second reason was/is that we wanted to be able to fly lower under the radar when parked overnight at non-campgrounds.... which we plan to do periodically in our travels.
