All Toy Hauler and Travel Trailer covers are 105" wide x 116" tall. To determine which size you need, please measure the complete length from the front bumper straight back to the rear of the RV. Be sure to include any spare tires or ladders in this measurement. This measurement should not include the front hitch. For complete height measure from the base of the RV to the top of the roof (exclude all AC units, vents, satellites, etc). Note: Although your model number may include a number, i.e. "32 DK", it may not accurately represent the exterior length of your trailer. Please measure your trailer as described to ensure the best fit.
