Yes Scott, this is Brian. The first and foremost, you got to talk about the top line. Obviously Q3 was a tremendous volume quarter. So we're covering up a lot of fixed overheads there. So when you look to the near term, obviously, we have a little bit of seasonality to work through. So, it's our I wouldn't expect our margins to continue to work upwards when we get into Q4. But certainly when we get back, at full throttle in Q1, Q2, and next year. I'm not seeing much that's different from where we are today. So as you start to break that down, you look at, our material costs, and our material costs have improved some in the last 12 months, but we've given over $30 million almost $30 million worth of price reductions to our customers, through the indexing arrangements that we have on steel and aluminum. So I would look at materials is not a significant driver to our margin improvement. Certainly on the labor side, we came out of Q2 position really, really well. Lots of efficiencies, we've consolidated a number of plants, labor was started out really solid. But now as everybody's aware, certainly within Elkhart County, labor's somewhat of a challenge. So we're working a lot of overtime, there are a lot of things that are, I think, I'd call them headwinds in the near term, until we can, identify ways to address the some of the labor shortages. Then when you look at SG&A, our SG&A was a little bit higher and Q3 than what I had originally anticipated. I mean, some of that's a lot of performance based metrics, as we came out of Q2, and now have better visibility, after getting through Q3, certainly on the performance based compensation side of things, whether it's equity, bonuses, etcetera, we had a little bit of a, some additional expense there. And then, transportation, transportation certainly been hitting us pretty hard, both inbound and outbound, just because of, a lot of the expedited freight costs that we have, and, and just the demand that's there. So those are certainly some of the things that I look at as the, the moving parts and pieces when we go forward. I'm not expecting significant changes here in the fourth quarter, other than volumes. I do think the seasonality you got to take that into account. But I think, other than that, we'll continue to address some of the labor challenges and some of the freight issues that we're seeing to help offset some of that.
