Description:
Trailer features include:
Axle configurations including: Spread axle, tri-axle, and tandem axle, with lift axle option. Several different mudflap configurations, and animated air bags for lift axle, and static axles. 
5 dump settings: 2-grain gate 25% and 100% lift, 2-full gate 25% and 100% lift and one called Area 21 for locations only tall enough for hopper bottoms (name is derived from the fact that I designed it specifically to work for a friend that uses the Area 21 placeable.)
Cover options: You can run without a cover, or add an animated rollover tarp, loosely based on a Roltec.
Dump sequence is animated, including deflating suspension, tailgate locking mech, and spin locks. Tailgate also swings freely after tailgate locking mech is released. 
Animated jackhandle for landing gear
Color selectable: 
Main Color: Pin plate, landing gear, suspension
Tarp Color
Capacity options: Standard 70k liters, Extreme 250k liters
I have plans for a few updates in the future, and I do realize that the trailer walks forward when tipped. I know there is a workaround to extend the a-frame during the dump sequence, but I am not a fan of this setup. If I can find a way to have the trailer pull the truck back, like in real life, I will add this feature. I learned a lot building this mod, and I still have much more to learn. I hope you all enjoy!
