I think there is lots of great info on this thread, I totally agree that Cataraftgirl could have the tongue extended... For FWIW, I was thinking along the very simple/cheap fix, potentially even DIY so wasn't thinking welders, sleeving, etc. Just drill 4 holes, add bolts and extend the wires.
Extending that tongue should probably be left to the pro's (though one could do it themselves.) Good luck with with the projects!
Paul7, Love that extender, simple, effective and removeable - ingenious!
