Hi, Took in my 2011 Forest River Berkshire diesel pusher with a Cummins ISB6.7 engine into Camping World for its first oil change at 4,000 miles. I like to make the first oil change early to remove any metallic particles or other debris from the lubricating system. The oil filter and oil was changed and the oil levels were dipped and proved to be normal, right at the full mark. The drive from Camping World to the storage lot (6 miles was uneventful and oil pressure was at 50 psi (30 psi minimum and no warning lights on. This last weekend on a short drive from the storage yard to my home (2 miles) to do some cleaning and prepping for our 5 week vacation, I noticed the check engine light come on when the engine went down to idle with oil pressure at 50 psi. When engine rpm increased the light went out. I re dipped the oil and it was at the full mark. The same thing happened again on the way back to the storage yard. The owners manual indicates that the Check Engine light on indicates the need for service. I cannot figure out what is happening with this and any help would be most appreciated. Fred

Hello, We are looking for a long weekend getaway from the Los Angeles, CA area to do a shakedown of our mew 38 foot class A. We were thinking of something on the coast n/o of L.A. but South of Morro Bay. We would appreciate any suggestions. Thanks, Fred Practicing for Retirement
