1.  Are the slides a maintenance issue to be concerned about and is a Newell with no slides going to be signicantly less trouble maintaining with regard to problems with the weather (leaks and debris, etc.) Yes is the short answer. Is it big deal, no. Replacing the slide seal is the biggest expense
2.  Is the resale market for a no slide coach considerably less than one with at least 2 slides. Depends on your definition of considerably. For example mid 90s no slide coaches with Series 60 engines seem to have stabilized in the 70 range, while two slide of the late nineties seemed to have stalled at just north of a 100k.
3.  Are the infrastructure components (generator, aqua hot system, leveling system, suspension, drive train & transmission etc.) vunerable for replacement in this vintage of coach (1995 - 2005).  Age is not too much of a factor on generator, AquaHot, leveling system, transmission, or engine. More use is better. Air bags and other rubber hoses and belts will need replacement if not done so already. Also, the radiator may or may not need to be replaced at that age. Take oil/fluid samples of engine and tranny before buying.
