i think a G40 bulldozer would be fun to use in BeamNG, you could crush cars, tow cars (if that is possible) or move wrecks off the trail and or road. Here are some pics and blueprints to save you the time to look for those
Its a special type of node which slides along an existing beam. Required in macpherson strut suspension and I was originally told that they would be required for tracked vehicles although someone else has now said otherwise. Regardless, we eventually need slidenodes for many vehicles to be added to the game and BeamNG cannot currently simulate tracks for whatever reason.
