I'm sure it doesn't take long, but i'm pretty sure that the Add w1 can doesn't have a a drain on the bottom. Thats why i wanted to add one, and if i add one. It would be just as easy to rig up a a remote drain line. So u don't have to pop the hood regularly on a brand new truck. I am not lazy i just like to make things easy for myself, even if it involves a hour of fab time. I have worked on every car i ever owned, and i am pretty annoyed by the fact that i need to do this to my brand new truck. I was hoping to avoid turning wrenches on this truck for as long as possible
