You do have a quick disconnect fitting under the front hood, it's brass and probably up and to the left as you are looking in. The fitting will accept a male fitting and you can use it to air tires or anything else. The fitting is there in case the coach needs to be towed, the wrecker will hook up air hose there to release the brakes. Do NOT use this air to blow out your water lines, it will contaminate them with oil. In our Tuscany I kept a 50' air hose with air chuck to air tires, 50' would reach everything. You didn't imagine anything, it's there!
