I have been looking at a short Journey and ran across I nice 40 foot Monaco we really like. It is both larger and has a bigger engine than we have ever thought we would consider. The engine is a 400hp ISL9 and vehicle GVWR is 35000 lbs.
Can anyone give me some idea of annual engine maintenance costs and what mileage I might expect; will be towing a CRV.
I see oil changes are every 12 months and I am wondering if that is necessary when using synthetic oil, or can an oil analysis be used to determine change time?
