Yeah. Thanks, Mike. Craig, we've talked a lot about the variety of decisions that we've made over the years. We referenced on the call today, in fact, the closure of the West Coast diesel production and moving that back to Northern Iowa. But – and some of the product line rationalization and emphasis on innovation, the Revel, the Class B lineup more broadly speaking. It's not just the Revel. Its several products now, and I think the EKKO Compact Class C continues to reflect that innovative spirit and capability of the Winnebago Motorhome team. And it's also some of the lean philosophies that the team has brought to – the layout, the space utilization in Northern Iowa looks very different today than it did three years ago even. They've gone from three production lines down to two production lines and increased the throughput, changed the flow of materials pretty significantly just as a couple of examples. Just in fiscal year 2020, they had over 100 I'd call it, meaningful cost savings initiatives that drove some savings. Just as a couple of examples in our Class B facility which is in Lake Mills, Iowa. We used to outsource some recovering of seats from the chassis that came in. We figured out a way to reconfigure our line, make it more effective and efficient from a space utilization perspective, and we in-source that recovering. That project alone saved, we think $300,000, $350,000. We invested in a CNC machines, in Chris-Craft and in-sourced some additional work there that project too, probably $400,000 of savings. But over hundred of these projects that the team executed just in fiscal year 2020 and these activities are what we are starting to see now materializing the results. Okay, we saw an improvement, as you probably noted in Q4, in the margins with the EBITDA margins. And then we saw another nice increase in Q1 here. Now, not to say that we won't face some headwinds, of course, ahead we know that there is some moving inflationary pressures and just as an example, we think that the supply chain has done a nice job of serving the industry. It's been a challenging ramp-up. They're dealing with all the COVID impacts like every other company. But overall, they're doing a very nice job in our supply chain team internally that Mike referenced is likewise, doing a great job. So hopefully, that helps provide some color, Craig, to why we're seeing the improvements here in Q4 and now Q1 and why we are raising our expectations, I guess, going forward.
