A log works because odors change with time of day, temperature, humidity and what you have just done. A smell that appears only after a hot shower points toward the bathroom. One that follows rain suggests a leak. One that follows the fan suggests the air system. Without a record, those patterns blur together and it is easy to chase the wrong cause.

Keep the log simple. Date, location, smell description and conditions are enough. Add a photo if there is a stain or a spot. If you hire someone, hand them the log and they can focus on the likely sources instead of starting from scratch.

A log also protects you from changing too many things at once. When an owner cleans the carpet, replaces the filter, opens a vent and adds a deodorizer on the same weekend, nobody can tell which step helped. Writing down each change next to the smell rating gives you a way to see what worked. It also makes conversations with a service provider shorter, since you can show dates and conditions rather than trying to recall them. Keep the log in the glovebox, a notes app, or taped inside a cabinet door.

If more than one person uses the RV, share the log so everyone records what they notice. Different people notice different smells, and a quiet observation from a passenger may be the clue that explains a pattern. Keep the entries short and factual, and avoid guessing at causes while you write. The interpretation can come later, once there are enough entries to compare. A log started now is also useful for the next owner if you ever sell the rig.
