Slides are going to limit access to under storage in a typical DP. Like an above poster my wet bay is between the slides.
But why consider what slide failure could suspend travel??? How many other one failure items can do the same? Probably hundreds consider: Dead battery, bad starter switch, many many feet of wiring, flat tire, any tranny item, any engine item, etc.
I spent hours trying to get my front slides in due to: A failed Lipper hydraulic pump due to 2 major issues - A poor seal design (motor flooded with hydraulic fluid) and a totally botched design for manual retraction. I jury rigged the pump and got the slides in and Lipper replaced the pump. Did I mention that the new pump was a new design that replaced the old failed design?
I think you get my drift.
