Short answer: yes. Though AirSkirts isn’t appropriate  for the elevated portion or slides of your fifth-wheel trailer, the entire base of your trailer can (and should!) use AirSkirts and you’ll get all of the benefits the product offers. While many fifth-wheelers choose not to skirt their elevated portion at all, you could investigate a more traditional skirting method for that portion – consider though that these areas do not typically have pipes that are susceptible to freezing and traditional skirts act more as a wind break and offer very limited insulating properties.
Because fifth-wheels typically have a higher ground clearance than other trailers, please measure the ground clearance and order a high clearance kit if between 21 and 32 inches. If you’re unsure or have a higher clearance than 32 inches, don’t hesitate to contact us!
