This is a complete overhaul of the older arrow board trailer I made all those years ago. It's been completely rebuilt from scratch. It consists of a basic frame, and a basic mesh, so it should be pretty easy on your computer.
CTRL+F1/F2 - Raise/Lower legs
CTRL+F3/F4 - Raise/Lower arrow board
CTRL+2 - Left Arrows
CTRL+3 - Right Arrows
CTRL+4 - Center-Out
CTRL+5 - Warn Mode 1
CTRL+6 - Warn Mode 2
Note: While the board and legs may be raised and lowered from the tow vehicle (if it has the forwardcommands tag), you'll have to manually enter the trailer to activate and deactivate the lights.
