I'd offer a caution on the SuperGlide if your family likes camping in smaller, more rustic campgrounds and state parks: you have to be dead-level to hitch or unhitch the SuperGlide because there's no pivot in the kingpin plate (obviously, considering the way the hitch works). I really liked the concept but we often find ourselves in beachfront campgrounds or wooded areas that are less than level. And I couldn't find a SuperGlide dealer who would tell me that it wasn't an issue, though most of them dance around it. If you spend most of your time in the larger, resort-type areas it's not a problem but I wanted to voice MHO for what it's worth before you plunk down a fistful of green.
