To find the fluid tank for the jacks takes two people.
One goes out side and LISTENS for the pump as the other one operates the jacks.. You should be able to find it in no more than 2 cycles of the jacks. If you suspect or have ever seen a can with a motor hoses and a bunch of wires somewhere.. Make sure you open that comprtment.
If I ever run into something with my coach.. The first thing that will break is the front fiberglass.. The jack pump is #2 on the list.
Home is where I park it!
