Do not recommend this product.
Do not recommend this product. This product is dangerous. Our trailer is within all the specifications listed. We read the instructions. We watched videos. We had 2 engineers using the product (one engineer who once worked for NASA), yet the only response I received is that we must not have used the product properly. Then I went and read the reviews on Lowes and person after person had the exact same issue we had. The trailer XL would roll out from underneath the trailer hitch. The first time it happened, the trailer collapsed falling to the ground. We were extremely fortunate nobody was hurt. DO NOT BUY THIS PRODUCT !!!!
