OK campers, I need some sage advice. I am at the stage where I want to buy some air vents for my 8A project. The Vans vents look like they would leak more than a spaghetti colander. The Stein's vents look good, and besides, we need to support Stein since he has new medical bills. My question, however, is whether I should purchase the 1.25" vents or the 2" vents for my ship. I like a lot of air, but the panel space is a bit restricted. Are there any folks out there who have any experience with one or the other? Is there any real diff? Thanks.
