I checked my notes and I used 15/40 wt. I believe all new Onans are prepped with 15/40.
Depending on where your located, no real extreme temps, 30wt is probably OK.
Do a specific model no. search for your 2800, I think different models had different recommendations.
In KS I would go with 15/40, and like what was mentioned, no longer than a year, or 100 hrs between oil changes.
