I run mine without all the time. However, car not driven in the rain. I can tell you with trays off you see heat rising from the bay. Has to help leaving them out.
Another tid bit---If you own Hex vents and use or dont use trays your hood liner if using an OEM hood will become soiled after time regardless. The hood liner soaks up the water and also the suds from car washes. Over time water stains will be present. Have yet to see a car with Hex vents not have this. Hoodliners are about $100 if occurs and picky like me. My new hood from MPD1 doesnt use a hood liner so no worries for me any longer.
