There is nothing in the world that these engines will "suffer" from using a 40+ weight. In some versions, it is required to use 5W-50 as a minimum spec.
An RV has no chance of getting good fuel economy anyway, so what is the point?
If there's no improvement in the next UOA, dump the 5W30 for a 5W40 or 15W40 with confidence.
5W30 is spec'd as the fill for a regular van. This van has had a house built on the back of it.
Great insight and info! I'm pretty sure I'll just dump the Pen PP in 2k check the UOA and try the Rotella T6 5w-40. I have two 2,000+ mile trips planned with in 8 weeks of each other and would like to do it on a better oil. What brand and weight are you currently using in your vans?
