Radiator Question for 98 Holiday Rambler Endeavor

Well the way these radiators are packed in there with the frame and the CAC from both my understanding from reading alot online and my experience so far in attempting to remove the radiator I see no real thorough way to inspect or clean. It is 22 years old and the hoses and other related coolant items do not appear to have been replaced with new when the motor was done in 2015.
