Owners manual for most brands of trailers (pop up, hybrid or travel trailer and 5gh wheel) tell almost nothing specific about the trailer. For example, it may tell you that you need to bypass the water heater when winterizing but won't say anything about where the valves are and how many etc. The suggestion about getting brochures and other literature on the appliances involved will probably give you a lot more useful information.

Check over at popupportal.com They have what you're looking for under the "manufacturers and manuals" section. We also did what others suggested here and went to the manufacturer's specific site to download information on the water heater, stove, converter, etc... We keep all of this information in a folding pocket carrier and it always goes with us.
