Interesting question on the load leveling suspension. I have the std suspension and tow ~5000lbs between the Aluma open trailer, race car, and supporting items. Rear end sag didn't seem too bad all loaded up. The inner tire wear was higher than I would have liked with equipment in the back of the car and ~500lbs on the tongue. My guess is the self leveling suspension will bring ride height back to where it needs to be and therefor the alignment as well. I am going to have the rear camber set closer to -1 deg and ease up on the toe to help with towing. Makes me wish I had spent the coin on the load leveling suspension.

All of that aside my X5d tows the rig like a champ.

Cheers,
Rob
