Fliegl Timber Runner Wide With Autoload

This set of two fliegl timber trailers is for those, who like original fliegl timber trailer, but cant load it with front loaders or big arm loaders. Every second partition was removed so there is much more place for loading / unloading. First one is 12m length (as original) and second is resized to 15m, so you can load up to 17m logs or 2 piles up to 7.5m.
