Exactly!!
Thank you Bear.
I'll probably try propping the toolbox lid open, to see what that does for me, since it's a simple, reversible test. I can certainly add more holes if needed, or enlarge these.
I'd prefer passive solutions, like a chimney, if required, vs "forced induction". I could certainly try a fan, and I have to expect it would definitely help, but at the same time, it seems like that shouldn't really be necessary, and it adds a layer of complication.
That's why I'm glad I never needed a Mailbox & I don't recommend one until there's next to no other solution to the AMNPS smoking problem.
The MES cover fits over my MES without having to undo a connection with a mailbox.
I don't need the extra room for the MB & the ducting, etc, etc.
To me adding a fan would be a PITA, but I like everything EASY !!! Kinda like the "Lazy Bear" you might have seen in my Step by Step Index.
