Bring clothes for heat, cold, rain, dust and anything else you can think of
Should be safe from defects with that setup, no fuel on site but a servo near by and plenty of large servos on the way back from some trips.
Moderate or Moderate + depending on your confidence would probably be fine, a lot depends on the weather though and some of the moderate + trips can require a winching if it's a little wet.
Trips normally head out around 9:00am, the camp site will be pretty empty after that so if you can't get there before the trips head out then take your time and grab supplies on the way in.
