We have extended warranty on a fifth wheel rv and had metal in the hydraulic pump but easy care wanted proof that there was metal in the pump so we authorized 3 hours of labor to prove that there was metal in the hydraulic system and they did find it so the jacks operate with the hydraulic system they need to be replaced and they don't want to pay for the replacement. Were afraid that we will be in the RV and the jacks will fall with us in the RV.
