Crankcase capacity
Cat C7 engine capacity listed at 19 qts ,if I put 2 qts (prefill oil filter) can I then put 19 qts in the crankcase I instead of the 17 that I've been doing ?

Depends. What year is your Cat? Does your engine have a slobber tube?
There are 10's of thousands of diesels in RVs out there where the dipsticks are marked wrong, so the engine blows oil out the slobber tube (newer engines don't have slobber tubes).
So if it's blowing oil? Use a quart less than what the book says. Still blowing oil? Drop it another quart.
In my Cummins, the book says 16 quarts. I run with 15 quarts...no greasy, grungy, messy oil on the back of the rig anymore. It always use to blow out that 16th quart so I don't bother to put it in anymore.
Plus what siggyd777 says.
