WW= winter weight.
I voted more than twice to abolish the obsolete SAE grading system and adopt Shannow's xW/HTHS method.

Either your friend is fibbing or I want the name of that engine builder! A big block that uses 1 qt every 4500 miles!
It's possible. A lot of the marine big blocks we do go 100 hours of a lot of high rpm operations, and we get out as much oil as we put in in the first place.
On-topic:
Those who are saying thick oil for the valvetrain are correct. BBC valvetrains are not exactly happy with constant high rpms, and a motorhome will give you exactly that. Consider 15w-40 your minimum. I'd run a 20-50 if it were me.
Using VR1 and Schaeffer 20-50, we've been regularly beating the wear universal averages while running the oil twice as long as the universal averages.
Curious.... I have a 94 Fleetwood Southwind Storm with a Chevy 454 TBI and I run only Valvoline 10w-30 VR1 racing with a Mobil 1 Exttended perf filter. I currently set the OCI at 4k or once a year. It's been a year today it only 1,803 miles. Planning a trip (08/14/17-08/30/17) to southern ca. From Seattle area. Should I just roll with it and change it when I return?

I would run it. No way that oil is used up. In a M/H the oil gets up to temp quickly, so any moisture(if any) is gone and the ad pack should still be good to run.

Run it and then change it. Are you running VR-1 Silver bottle, or Black bottle?
There are some VR-1's that are not appropriate for daily use. The add pak is for racing use only and assumed changed after each event ... It's excellent oil, it's the add pack that needs clarification ...
If you want to run a 30 multi and a longer life oil, you might consider Chevron Delo 15W-30 SD (severe duty). It's also an excellent oil. Just an option
All these motor home engines tend to spin and run a bit warm. It mostly depends on how well the MH MFG implemented the cooling strategy ... My bud's is a nightmare with A/C condenser and oversized tranny cooler all in front of the radiator
We've been moving things around to actually cool that BBC some
