O.K. thanks to all for input on the levelegs issues. advice to change out has been frequently heard. I have rear jack removed-will have motor integrity checked and re-install. Still issue of bending pin in jack stem-maybe affiliated with air dump mode being improper? Will set dump mode parameters and try system again. Goal to get workable enough to pass buyer inspection (will be honest with buyer and suggest trip to HWH installer).Don't desire to foot this bill which could not be recovered in resale. some further questions: Do you have knowledge of reputable HWH installers Ohio or Indianna I can suggest?
Do you have knowledge of reputable shops in same geographic area who work on interiors (gap in seam of bedroom ceiling)? Do you have any knowledge/experience with company called RVSelect (FL)? Many positive reviews on their website. Thanks again to all. Sorry for all the questions, need your collective knowledge.
