Loading up for towing

In a few days we'll be setting off on our first ever caravan trip. We have been taking "stuff" up to the stored van over the last few weeks and it now contains everything we'll need other than clothing, towels, and some food - this trip is only for three nights so this won't amount to too much.

Our payload limit is 350kg - we'll be way under that and our noseweight limit is 75kg which we are also way under at 55kg.

We have been putting most stuff in the high-level lockers and the bulky items like folding outdoor furniture under the fixed bed. The porch awning will go over the axle.

Should we be using the high lockers or bagging/crating things and using floor-level lockers while towing?
