Sure. So, let's start at the kind of bottom and work up here. On the Tropos side, it's been a challenge on the supply chain, getting the kits in, so we can turn them around and finish them. That's -- once we get them, we can turn them around very quickly and get them out the door. We do expect it to ramp up in the third quarter versus the fourth quarter or versus the second quarter, but not to the point where it is game changing on the revenue. Remember, one of these trucks, because it's -- we're assembling them, is dramatically different revenue convert compared to one of our trucks. So, we do expect continued growth there. But in terms of modeling out, it's not huge dollars there. Next up the list is, we've broken through on our first drone sales, but really getting those to scale, while I think it'll be significant progress this year, it's not a big contributor to your revenue model. Now it gets us into the trucks and there, if you think about the four, really four versions we're focused on, you've got the Class 3, 4, cab chassis, the step van in the Class 3, 4, step van in the Class, 5, 6, and then the strip chassis on the Class 5, 6. And as we start to turn the cab chassis, as build slots become available and credits, et cetera, we expect that to be a significant contributor. And then, of course, the step van and the W56 is to be the real linchpin. So, those are the two keys, those two vehicles, and then the 750 and the strip chassis will be important, but not as important as the other two.
