If you have a place to store it, an enclosed trailer is a nice way to go. You can leave your support gear, pop-up, table, chairs etc. in it. Fuel doesn't stink up the car. At a contest, you have a place to set your plane, out of the sun, rain wind. My use is primarily for FF contests so the chase bike is stored in it, not taking space in my shop. Many trips down I-5 to Lost Hills, you run at 63mph (posted 55 for trailers) or the trucks will run over you!
