Dual pivot vs Single pivot Fifth wheel Hitch

Real world experience: I went on a hunting trip one time and set up camp on uneven terrain. I had a two way hitch. I could not get the pin to align with the plate at all. I finally had to unhook the upper section of the hitch, hook it up to the kingpin, then use the trailer jacks to drop the hitch back onto the lower section. It took over an hour to hitch up.
