Hello,

this is an 8x8 recovery truck or wrecker which is used to free stuck vehicles or tow broken ones. It can use its crane to move objects, too.
It basically is a tow truck for military applications.

I made two versions, one in "drive mode" and one with outriggers extended and crane unfolded.

There is a command block in each version that summons an invisible armor stand wearing gold armor in case you would like to summon the armor stand again.

Before you paste the schematic make sure to set //perf update and neighbors to off and paste with entities (//paste -e).

Enjoy!
