coming back to my last post, I still think that there is air in the system. on the last test drive we didn't put a cap on our power steering reservoir and air was coming through and throwing out fluid. we have not driven since then but i believe that driving will fix the problem... i.e bleed the system.
As i said in last post my most recent project is completely sealing off front end, and configuring dash wiring, starting with putting 18 gauge steel under floor then sprayfoam. on top is then plywood, which should totally seal off all leaks. I did rebuild the stairs, however they are almost same as original, for a few reasons. i did make it so rise is same for each step. And we also still hope to be able to fit spare tire underneath. did widen the 4th step up, making it a little wider towards the curbside of bus for better accessibility.
I'm now doing wiring in thefront so i can insulate front bulkhead, which should be almost the last thing to insulate.
We also have new windshields, at somepoint we will start putting them in and tweaking things so they fit. (the frame not the windows. windows dont tweak

And also some more insulation in the genset compartment.
And we are working towards getting levelers going.
