Well, it's an issue - it was an issue throughout the quarter, right, and it wasn't just one OEM, okay. What you have is the suppliers, if you go back a few decades, there were many suppliers. The consolidation of the supplier base for the OEMs, right, because I don't care which brand you talk about, they may all get the same panels and things like that when I'm talking about interior pieces and stuff like that from the same books they're made and supplied to them. You had a large - there was a large bottleneck around that and it was varied from different components. Now, does it get picked up, you know, we - does it get caught up, eventually does bring someone else pops up, right, we have another supplier pop up and it less what we've seen. I do expect it to get caught up pretty cleaned up by year end. We're still experiencing some slowdown in getting product, because it's going to be short, I don't say short shipped, but it will be - it will come offline, there will be short of pieces because those components were available, right. So that just delays the delivery to the end user and that's what we've seen. That's what when I say I expect our fourth quarter deliveries to pick up, but there's more fleet deliveries inside there and at the same time, we're catching up some of the stuff we believe that we were short on in the third quarter, that should've gone up in the third quarter. So, we believe it's going to get caught up, but it's still - I know what something that popped up two weeks ago with another component, right. And you get one thing clear and then another component of those OEMs come up a little short on the others, but you don't get caught up. And I see something - I have seen it before during these types of cycles, again it's part of the cycle, it's not happened back in - it happened back in '15 - when we have - when they were doing 57,000 units, that year it got tight, it's happened in other cycles when you want to accelerate. It's just really hard when you have such volatility sometimes in the sales with the Class 8 truck market going to have some heavy volatility in. It's hard for the suppliers to keep up when you hit this part of the peak cycle, but they always get caught up.
