Does anyone know if JConcepts Over Tray has any vents?
If none, where would be the best place to make them?
No vents, but you can make them. I bought the tray when they first came out, was not impressed with it. I would look at a mesh shroud instead, just my opinion.
Cheap, Fast, Reliable. Pick 2.
Was it trapping a lot of heat?
I found it very limiting. Anything that stuck up too high caused it not to fit correctly or required it to have holes cut in it, which negated the purpose of it in the first place. Get a dusty motors shroud... they work great. They're mesh so they breath but theyre a waterproof mesh so water and dirt/snow doesnt get through. Very impressed with their products.
Thank you for advise.
