Using this 2001 Sherman & Reilly DDHA - 75T Duct Dawg Underground Trailer is straightforward. First, make sure you've got the right equipment to connect to it for the pulling job, as it can handle a max pull line of 7,500. When you're ready, hook it up properly. As it's a used trailer from a working environment, it might have some minor scratches and scuffs, but that shouldn't affect its performance. Just be careful during the pickup. It's available only for local pickup at the MSU Surplus Store. For maintenance, regularly check the connections and make sure there are no loose parts. If you notice any new damages or issues, it's a good idea to have it inspected by a professional.
