I am new to having a diesel pusher, mine is a 2008 Tiffin Phaeton tag, it is on a Spartan chassis, I have been told that I should once a year take it to a Spartan authorized dealer and have a complete going over the chassis plus change the oil and all filters both in the motorhome and the generator.
The generator has 1100 hrs on it and I have been told I should also change the belts. They are talking 800 to 1000 dollars for this and I just would like to know if members believe this is necessary, I only use the MH for about three months in the summer and this past year drove about 6000 miles. The engine now has 50,000 miles on it. I had it completely serviced Jan 15th 2015.
