When I look over a unit for sale on a pre-buy, I'm looking at the maintenance records for regular service. Oil, filters, chassis service, genny service. etc. There's a whole list of stuff that should be done every year, twice a year, every 24,000 miles etc. If the receipts for these are in a 3-ring binder in chronological order, I know that the current owner understands the meaning of preventative maintenance.
There's an entire generation out there that has not even lifted the hood of their car. PM means taking it to the dealer when the check engine light comes on. You can't treat a motor home or camping trailer that way.
It sounds to me like you're interested not only in preventative maintenance, but also very careful bookkeeping. The latter may be good evidence of the former, but in itself it doesn't have any bearing on how well maintained the RV is.
I'm afraid I don't keep receipts from Walmart for the oil and filters I buy just to prove to the next owner (whenever there will be one, which I don't expect for some time) that I did indeed change the oil as specified by the manufacturer.
