It's great to see Toyota supporting this event. I've said it before and I'll say it again. I think on a proportional basis the 200 series Land Cruiser gets built and wheeled more than just about anything on the road in the United States. People would immediately assume the Jeep Wrangler would earn that spot, but looking at the sales data is interesting.
Jeep sold 1.45M Wranglers from 2008-2017, whereas Toyota sold 28k 200s in the same time period. Including the wait list for LCDC, about a hundred 200 series want to show up and wheel their trucks in Ouray, most of which are built to some degree which means 0.36% of all 200s sold in the last decade in the US want to show up at this one single off road event. That would be analogous to over 5,100 JK Wranglers showing up to a single event. Just looking at the number of built trucks on this site shows, in my opinion, a fairly significant proportion of owners who modify their 200s. I would estimate at least 4% of 200s get built and/or wheeled (~1,100 trucks from 08-17), and that would mean proportionally speaking over 57,000 JKs would be required to get to the same proportion. I know there are a lot of built and wheeled JKs out there, but I think purely on a percent of ownership basis the Land Cruiser gets "used properly" more than Wranglers, 4runners, Tacomas, etc.
Now keep in mind this is 100% speculation, and I have no empirical evidence to support it. I started wheeling Jeeps when I was 16 and have owned and wheeled CJs, XJs, ZJs and a JKUR, and I've had a 100, 3 200s, and a Tacoma all of which were built and wheeled. I have found the 200 series community to be the among the most eager to build and wheel of them all, which is amazing when you consider how expensive the truck and the mods are. The community is also one of the most supportive and enjoyable I've been a part of, and that extends to even more clubs I've been involved with including Porsche, Audi, Ducati, Tesla, etc. The 200 enthusiast crowd is a great group of men and women, and I'm happy to see Toyota recognize that as well. I can't wait to see the 300 and hope it continues the tradition of what's made the 200 such a solid platform.
