Kitchen/Pantry
A travel trailer often comes equipped with working appliances, which may include a microwave, mini stove, sink and refrigerator. Because of this, you may wish to stock your travel trailer with utensils that allow you to make full use of the kitchen. These may include a rudimentary set of cookware and cooking tools, as well as microwavable bowls and reusable plates, silverware, cups and bowls that are suitable for eating off of. Food may include nonstick spray, lunch meat, spices to cook with and staple items such as milk, eggs, cheese and butter. Since shelf space within your refrigerator is limited, most food should consist of dry items that store easily within your travel trailer, such as dried soup, coffee, rice, cereals, Bisquick or other batter mix, pasta, bread and dried foods.
Linens
Many travel trailers include a small bathroom with a shower. And even if you are taking advantage of rest stops or public facilities, you will want to stock your travel trailer with the supplies that you need to bathe or take a shower. This includes toiletries and towels. In addition to towels, basic linens that you will want to include in your travel trailer include bedding, beach towels and hand towels for the kitchen. Before you head out for your trip, you will also want to stock your closet with a range of clothing suitable for the duration of the trip, including bathing suits, cover-ups, casual shirts, shorts and pants, undergarments, water shoes---which may be worn in public showers---hats and socks. Bring laundry bags and laundry detergent, too.
Miscellaneous
When stocking your travel trailer, you should take into account the various activities that you plan for your vacation, and stock your vehicle accordingly. If you enjoy board games, you should include some in your trailer. If you like to read books, include a book or two. Other items that should be included in your travel trailer include a first aid kit, roadside assistance kit, insect repellent, hand sanitizer, clothespins, batteries, maps and GPS, a radio, an alarm clock and a cellular phone for emergencies.
