Gary, you can contact Fleetwood with your VIN and they will provide you with most of what you need. Wiring, plumbing etc. Same with Freightliner for your chassis and Cat or Cummings for your engine depending on which you have. I would also encourage you to join Discovery Owners Association (DOAI). Google Discovery Owners and you can find the site. The support from other Discovery Owners on the forum is priceless. Also camp Discovery in Seffner Fl is well worth the trip. Also if you with to talk offline let me know glad to help. Good Luck
