2017: “Radiator tank started leaking at a rate of over 15 qts per hour on trip to florida. Kept filling with water to get 2 hours to final destination. Replacement of radiator was done at north trail rv in fort meyers at my expense of $6,195.34. Spartan motors is the manufacturer of the chassis and this is a well known and documented problem with api radiators. They have replaced many of them to date, my coach was just 6 months out of warranty and they said they would help me out they offered $1,000.00 against almost $6200 bill. …”
