You need to ask your self some questions, do I need the extra room? Were are we camping at (some campgrounds can be very tight). Are we going to drive to a campground and stay for a time or drive around every couple of days. While asking that are we going to drag or drive another car/truck/suv?
Slide have been around a long time for sure, and there is must have maintenance that must be done for sure. Other comments have listed some positive and negative for each. But it comes down to what do you need!!!!
Wife and are are looking at class C/B+ units with slide and no slides we plan on driving around from place to place not taking another car/truck/suv in tow. I am more looking at NO slides!!
