Yeah I'm not buying that either. The picture even looks wrong. It's a road truck stuck in mud. It probably helps that you have the back loaded, but still I bet that truck is barely moving if at all.
i have towed the skidder 8400 with the LTL 9000 through the swamp as did my buddy following me and he was using the freightliner and towing the skidder aswell.
i also had a load of short logs on the LTL 9000 and it was just crusing through the mudd.
me and bud just did this , we towed the 8400 skidder with the LTL and freightliner.
i was in the LTL and he was in the freightliner,
we went through swamp on grizzly creek and logmore, and had no problem,
also i put the short log cart on the LTL and put the B130 in the back with the fuel barrels in the back of the B130 and the LTL went through the mud like it was nothing.
as for the k8400 skidder being not able to load trucks, its easy, with shorts and long logs,
just turn the logs straight with the skidder and back it in to the trailer,
as for the WS i dont think its that good, just seems slow and underpowered
