Sorry I couldn't respond to the insulation post, but I had to work late the last couple nights.
Good call on removing the nasty yellow foam. I can't really help much on how to get it out since when I found out my double door had foam. I ditched the smoker idea and made it into a dry storage unit for my trailer.
Sounds like you got all the info on the electronics stuff, thats all greek to me.
The door gasket can go a couple ways, high temp RTV sealant and wood stove rope gasket works good.
Green egg felt works good to, I hear.
I try pretty hard to respond to all the build thread question, if I miss one and you aren't getting an answer, just shoot me a pm.
I can browse and post from my phone, the PMs show up without hassle. And I can try and get you an answer.
But just checking new post is a giant pain in my back side. ( I sure wish they could add a new post feature like ALL the other forums us on mobile sites.)
For the admin,,,,,, if hudler could figure this one out, we could get several more members. Tons of folks only surf and post from there phones. One look at this forum on tapatalk and they run away fast, its in the dark ages.
Forgive me for the off topic rant but I felt that if the add on worked correct, the insulation question could have been answered the same day.
