I assume cost is the main reason so many pop ups only have 3 jacks, but of course any three points are always in the same plane. with 4 you'd probably need to move from jack to jack with less raise on each one, right? My one side jack may be getting soft at the mounting point, and was thinking about getting one more to have them at all the corners.
Thoughts?
TIA.
