I keep an extra set in the camper just for this eventuality. In fact, I keep an entire outfit in the trailer; underwear, socks, t-shirt, sweat shirt, jeans and shoes. I have a paralyzing fear of forgetting my clothes (it's silly, I know).
Anyway, as to the original point: Since our trailer lives in storage with no power, we cannot keep consumables in there. So we use those reusable cloth grocery bags. We have one that lives on the coat closet right by the back door, that's where we put things we don't want to forget next time we have the trailer. I can carry at least 4 of them in one trip if I need to.
We make a meal plan ahead of time that includes a "grocery list" and a "from home" list. When we're buying groceries, we make a special trip to the store just to stock up for our trip; those groceries don't go in the house, they go straight from the car into the camper. We bring the trailer home from storage a week before we leave to cool the fridge down (we have 50A plug at home) and conduct any maintenance or repairs that need to be done.
The rest of the food that comes from our house is on a separate list. DW and I gather in the kitchen, assemble all the things we're bringing from the kitchen, load it all in those cloth bags, and shuttle them out to the trailer. Usually it's only one trip. Our clothes and toiletries are another trip. Truthfully, I'm happy to go out to the trailer for any reason, so I don't mind making more trips.
We have laminated lists that we've made up based on past experience that include things we know we are likely to forget. Between this and having a written meal plan, and grocery lists, we haven't forgotten anything in a long time. All lists get reviewed prior to departure while the truck is hooked up and running (we have a laminated list for towing, setup and teardown as well).
When we get home, all the consumables go back into cloth bags and get shuttled into the house, all the laundry is in a "barracks bag" to go in the laundry room for cleaning, and our toiletries are in travel bags and go back into the bathroom for re-stocking so they're ready for next time.
