NOW this thread is posted! we were hooking up to leave MI. last week when my jack stopped mid lift and we still had power at the jack for the light so I tracked the wire and found that was not the problem. but the foot was to low to tow so now with all ready to leave to FL i had to get a bottle jack and blocking to lift the trailer off the jack and unbolt it then lower the hitch on the truck 2 diffrent lifts and then latch and lift again to hookup the wdh bars and finely lower to remove the bottle jack. what did we do with out cell phones called CW and found a new jack on the way ,bought it and had the new one on the trailer by dinner that night. will take the old one apart when back home to see what went wrong. gotta love camping!
