Welcome to the club!
Since you're new to the brand, I highly recommend you check out the "New to Subaru" thread
as well as the break-in procedures
if your Subaru vehicle is still within the first 1000 miles, if you haven't already.
The Honda Passport is essentially an Isuzu Rodeo, so I think it's safe to say you've got quite a bit of experience with Isuzu's passenger vehicle offerings.
Besides the skid plates, you also may want to consider switching the tires to all-terrains, if your thirst for adventure is strong enough to overcome the stock tires.
