Look, I think 2019, 2020, really when you think about it, over the last 12 months, there's been over 500,000 net orders have been booked, which is a new record. And the backlog, as we sit here today at the end of September early October, was almost 300,000 units, 286,000, and that was a new record and the nine-month build rate was only 241,000. I think they are estimating about 310,000 to 320,000. So, again, with retail sales up 28% and I think the forecast for ‘18 would be 315, there's no question that the sales could hit 320,000 to 330,000 units next year. And what's happening is ELD are three letters people probably don’t know about on the phone is electronic logging devices. That means every driver has to electronic report his drive time to the federal government where they used to have logbooks; they filled out and typically had two of them. Well that's all gone by. So, there's been a shortage of equipment, the owner operator. So, that's put pressure on these fleets in order to buy trucks. We've even seen our rental business had PTL running in the mid-90s from a utilization perspective. So, that’s put pressure on it. Then, you look at just commerce, e-commerce. Today, 85% of all goods are delivered by trucks, either light, medium or heavy-duty, and there is pressure on those obviously with this one-day two-day delivery, which certainly is key. The good news for us is that the byproduct will be on a longer-term basis is the parts and service business it comes out of this. Units in operation with Freightliner with the highest percentage of 40% of the market, this will give us a strong parts and service follow-up and flow through for us over the next 3 to 5 years because typically these trucks run anywhere from a 100,000 to 150,000 miles, and puts us really in the sweet spot when you think about it. So, to me, I think we’re in a good shape. There's no question in my mind in 2019. And I'm also looking at 2020, because I can look at that pretty much from the standpoint of Penske Truck Leasing who spends about $2.5 billion a year on equipment. And we’re seeing more and more people having to go to new equipment. And they are driven for a couple reasons. Number one, emissions, the new emissions capability is less complicated; and also better fuel economy. And to me that's amazing. We’re up to 90% utilization in our fleet at this point.
