I realize this is an issue with the motor, not the actual motorhome itself, but before I start looking at possible issues, I was wondering if anyone has had this problem with their chevy set up before.
Obviously it is something that is getting wet, like the coils.

For beginners, open the air filter case in the passenger side front wheel well and see if the foam filter has separated from the paper element and might be all bunched up in there. It should be cleaned and dried out either way.
I found this once in a downpour and while staying in a wall-mart that night, found a filter in the store, then cut and glued on some new foam which was much cheaper than finding one like the OEM at a dealership or even NAPA. No matter what, water will get in here on occasion and am still not sure if it comes in the intake in front of the radiator (most likely) or works it way in under the filter box cover.
If your check engine light stays on after you're done, disconnect the chassis battery for a few minutes to reset it.
