I made this with help from Crazikyles Figure 8 mod and off of Gridmap as a file base. This is a pack of mods that includes the track and 10 race scenarios, 5 configs in forward and reverse direction with waypoints. The floor looks messy but it was so that I can give the mud depth to make lots of rough bumps. I hope you will have fun with this. I have put it here as I thought that uploading all 10 scenarios would annoy people. I have a live post up at the moment asking about how to package it all together as one mod but no one has replied yet. https://www.mediafire.com/?uqq4x814aw1u2xk http://www.beamng.com/threads/help-with-assembling-a-campaign.32450/
I am still getting to grips of the file layout a bit. I have put all 11 .zip's of all the scenarios into a zip and the game will not read them all from one zip file. Thanks for your comment
All fixed and done. Here is a link to the full resource where you can get the campaign. http://www.beamng.com/resources/tanner-gulch-dd.1573/updates
