Speedco Oil Change cost

Just took the motorhome to Speedco this morning for an oil change. Had the following done.
Oil Change Cummins 8.3 ISC (approx 21 qts)
Oil Filters
Fuel Filter.
1 gallon Coolant
Oil Analysis
Purchased an extra gallon of Shell Rotella 15-40 oil to carry with me.
Generator Oil Change Onan 7500 watt
Oil and fuel filter
Topped off coolant
They also lubed the chassis, and checkked various fluid levels
Total price was $317.76
Personally, I think that's a very fair price.
I had a shop quote me $450 for engine oil change and lube.
