I'm needing to get this problem solved soon. I bought 4 Rieco Titan 2k camper jacks for my slide in camper. At it lowest setting, the Reicos are only 30" from the floor. I'm needing it to lower further because I'm wanting to put my camper on a dolly that is only around 10" off the floor. Any solution to this or are there other jacks that will lower the camper all the way to the ground? Thanks,. Joe
