milage on a diesel engine
I am considering purchasing a Class C RV with a diesel 7.3 L engine with 150,000 miles - What is considered excess mileage? I know diesels are suppose to stand up better than gas engines? Is 150,00...

That is not too many miles on the 7.3 diesel, oilfield service fleets around here operating the type usually traded at around 200,000 to 300,000 miles (which might be 3-5 years).
It depends really on how many more miles you plan to put on it. At 5000 miles a year you could be looking at another 10 years of service. 50,000 miles a year, maybe a couple more years. Even then, what is going to be wearing out will be drivetrain parts behind the engine, not the engine itself.
As others have noted, for a C motorhome with that many miles, you need to be looking at the condition of the house. But even there, a lot of time on the road is not necessarily an issue, some RV rental operations used to order C motorhomes constructed such that they could lift the house off a worn-out chassis (200,000 + miles for gassers) and drop it on a new one.
