I have contacted Keystone a few times asking if schematics and or drawings are available...even for purchase. I received an email from a young lady named Cheryl Clayton and she said "I regret to inform Keystone does not have wiring or plumbing diagrams available, due to the rapid changes done to our units. "
Personally I think this is, how do I put this... WRONG. RV manufacturers and dealers hold you hostage by not giving information while holding your RV sometimes for weeks and possibly months trying to fix a problem.
Like most RV folks, we just want to understand how our RVs are put together. If something is broke...sure I'll take to the dealer and have it fixed. I just want to make sure it is actually broke as well as better understand how my RV functions.
