Does anyone know how the 2010 Tiffin Phaeton 40 QTH measrues up regarding adequate CCC and Torque? Does it have adequate CCC for full timing and is the HP/Torque adequate to tow a 5500 lb vehicle in mountains? Comments?
I have a Tiffin Phaeton 2008 purchased in August 2007 which is now 8 years old and has 56,000 miles. It is on a Freightliner chassis and has Cummins 360 engine.
Manual says the transmission fluid should be changed at 150,000 miles or 48 months and to replace coolant at 100,000 miles or 60 months. This coach is 84 months old but does not have the miles required for the change.
Should I change these now based on the months or change later based on mileage?
