I have a 98 Class A with Hwh 310 hydraulic jack system.
The jacks will go up and down to the ground OK, but wont lift the coach.
It seems to me to be a relief valve bypassing or weak pump(rare).
Anyone have any experience with this issue and how to fix ?
I have called HWH but they tell me it will be weeks before a tech can return my call - it has been 4 weeks now and still no call!
They won't even return call to a repair facility I took it to. This company has the worst customer service I have ever experienced.
I wonder if they are going out of business.
I would appreciate any help you can provide on either of these subjects.
