Travel trailers range in size from 18-24 foot compact models to full-sized equivalents to Class A motorhomes. Travel trailers are designed to be pulled behind tow vehicles with load distributing hitches. Depending on its size, a travel trailer can be pulled by full-sized sedans and SUVs to vans and pickup trucks. Because they are towed, travel trailers provide the option of parking the RV and using the towing vehicle for short trips and errands.
