Camping trailers are available in a wide variety, from "eggs" that are simply a bed and a roof over your head to big fifth-wheel trailers that can house a small family and carry several all terrain vehicles. Determining what you need out of your trailer is an important first step. If you're already used to camping out in the elements and you're just looking for a "home base," then a small trailer or a pop-up trailer should cover all your needs, such as toilet and kitchen facilities, storage and a shelter when necessary. A pop-up trailer is a small, light trailer with a tent that self-erects. When towed, it collapses to only three feet high. If you camp in areas with strong weather or extreme temperatures, they are not recommended. If you want to camp in style or if you plan to camp with larger groups of people, then a larger trailer is recommended. Keep in mind that cars will need a tow bar installed to pull any trailer, and they are only capable of pulling smaller trailers. Larger trucks with special tow equipment as well as a commercial driver's license are necessary for hauling large fifth-wheel trailers. Several companies rent vacation trailers, and this is a good way to get to know which trailer will work best for you.
A comfortable camping experience depends on your trailer being reliable, so make sure to give it regular attention. Drain the fresh water and sewage tanks after every trip. If you store your trailer in an outdoor location for extended periods of time, be sure to take all the upholstered items, such as pillows, indoors to keep them from getting musty. Especially with pop-up trailers and in areas with constant humidity, keep an eye out for mildew. Mildew in the canvas of a pop-up trailer can make it an ineffective shelter quite quickly. Mildew in or on another trailer can smell unpleasant, negatively affect breathing and eventually damage structural integrity. Mildew should be treated with a light bleach solution, made of one part bleach or another similar cleaning agent to 20 parts water.
One of the most important factors in camping in general, including camping with a trailer, is planning ahead. Your trailer must be prepared for the maximum use you could put it through. Will your trailer comfortably hold you and your three friends if it rains for the whole weekend? If not, make sure you have a portable shelter as well, for extra space. Fill your propane tanks before you embark on any trip, as it keeps your heat and air conditioning runnin, as well as powers your stove and refrigerator. Fill your fresh and gray (non-drinkable) water tanks before you travel as well. Very little is as unpleasant as running out of a necessity while camping. Finally, just in case, make sure your trailer is stocked with extra food and supplies as well as diverting activities like board games.
