Driving cross country in my '13 SAP this summer for two months before we move to San Francisco. I was looking to pick up a cargo
box (e.g. Thule Sonic XL Silver) but at 46 lbs, that only leaves just over 100 lbs for storage (Factory cross bars can take 150lbs) which can easily be eaten up by 2 - 3 duffels of clothing / gear. Aftermarket cross bars don't seem to offer much more than the factory cross bars, so doesn't seem worth the money for a few extra pounds of capability.
I'm trying to gauge more seasoned Outback owners to get a sense for whether this limit shouldn't be pushed at all, if gear weighing in at 150lbs is ok, or whether it's a conservative limit and it's safe going a little over.
What are your thoughts?
