What is painfully obvious in this thread and thousands of others - don’t go to the stealers!!!!
I appreciate the OP’s dilemma as the last time we went to a dealer, 4 mnths later a call to pick up our RV got us excited for the road. Nothing had been done. Uugghhh. Never again.
Hydraulics are not complicated. Any good shops in your area for big equipment? Like a CAT dealer, Hyundai, whomever or a Princess Auto? They would have someone who actually knows the tech to fix it or walk you through the steps in a way your comfortable with. Maybe.
Really hope you can get it sorted and get back to enjoying life.
