This is my next version for BAC. It uses the "Roach" for filling the container. I figured out the code to allow tree trunks and slender tree trunks as well as the original logs.

// Sledwagon
// Integration of Galgana's Cethegus sledwagon reborn
// Itself drawing on ideas from Privatter's quiver mod
//
// from https://www.unrealworld.fi/forums/index.php?topic=5673.0
// adapted to BAC with minor edits, wheels now madatory
// Sled build time longer from 1h to 2h
// Load efficiency is 1:20 original.
