If you smell tank odors inside your motorhome, there’s a good chance that you’re having a
venting problem caused by outside air blowing down the vent pipe. 360 Products Inc., known
for its first rotating vent, the RV-360 odor extractor, has simplified the process with the
360 Siphon. According to the company, the design of this non-mechanical vent cap – which
features no moving parts – ensures that there is low, or negative, pressure at the stack
opening in all wind conditions, allowing any slight wind to pull fumes from the waste
Available at Camping World ($26.10), it includes a built-in bug screen. 360 Products, (866) 467-8360.
