FP Trackmaster

I don't even know what to call this, its a thing with 2 bogies of tank tracks and a large platform. There are 4 configs, a default config, a config with a 24 ton capacity crane attachment, another with a plow, and lastly with a heavy load. The tracks are really fun and realistic, and this is overall a great albeit old mod. The only downside is lack of interior detail, with not even a steering wheel.
