Casita travel trailers range in size from 13 to 17 feet long, making them small and lightweight enough to tow with a variety of vehicles. The compact size of the trailers allows them to fit in small campsites, and the fiberglass construction is rust-proof.
All Casita models include a bathroom with a toilet and shower, as of 2015. The trailers maximize interior space by converting the dinette to a bed, and several models hold a maximum of two people. The Spirit Deluxe line sleeps up to six people, and one floor plan offers bunk beds. All models come with a two-burner stove, and some models have space for an optional microwave.
