My 2-cents would be: Plan to leave almost everything in the trailer, so it is ready to go each time, without lots of packing. Get one plastic box with a lid, and use it for EVERYTHING that won't stay in the PUP. If it won't fit in the box, you have too much stuff.
The things we had in the box were: hand-towels (they had to be laundered), syrup, cooking oil. Before each trip, the box got filled with bread and other food items. We left the syrup and oil in the box, and put the pillow cases and towels back in there as soon as they were laundered. We made a list of what we needed to replenish, and it was put in the box within days of our return (paper towels, foil, etc). This way, you are not doing all your packing at the last minute.
Enjoy your new weekend home!
