Don, per Paul Maddox of HWH, check fluid level with your rear slide in and your front slide out. This is specifically for the HWH "train" system we have in our '02 and '03 models, in which the front slide mechanism retracts its rams in order to extend the slide. I'm sure you already know this, but just in case: per Paul, fluid should be between 1 inch and ĺ inch from the top, any excess will be pushed out onto the reservoir top (not a mechanical problem, but creates a mess). Paul just makes sure the reservoir cap shaft is wet on the bottom.
