Most try the custon cone grind for a time then upgrade to the foot grind (shortening). Still, if all is well and the clutch has been upgraded and the turbo/injectors etc. etc. some will remove the foot completely.
If your towing heavy loads, the engine will require much more air in the way of free flow air inlet (to turbo) and a larger compressor..... exhaust system upgrade, to prevent melt-down.
