That lip won't keep out more than a drop of rain. It is there to allow the install of a bug shield, which hangs on the lip and is secured by a spring. The difference in length is probably to allow it to fit in the new furnace and not the old one. Chuck
The lip isn't there to "allow the install of a bug shield." The furnace manufacturers specify in their manuals to never block the exhaust or intake of the furnace with anything, including screens.
Wow, Most every RV supplier out there, including Amazon must be totally unaware of that, including us and most RV's we have seen.
