Custom Condor Chocks

We got rid of the old school chocks and replaced them with a fully adjustable set of Condor Chocks paired with the airline track adapter kit.

Stainless Steel Side Trim

A unique and stylish optional feature that is just another reason this model stands out from the pack.

"Thanks Ryan. I appreciate all your efforts. The new trailer is amazing with the red cabinets and coving. I will always recommend Complete Trailers to anyone looking for an ATC trailer. I have had many compliments on our trip to AZ. Pulled great behind our 40ft Tiffin coach. "
