Being at the house provided a good opportunity to change the oil in the RV. It was time to do so right at 130,000 miles. The last time I changed the oil we were in an empty forest service campground in Missouri. I had bought a oil catch basin from Walmart along with ten quarts of oil. Try as I did to be careful I still had a major oil spill on the asphalt pad I was parked on. I had neglected to pop open the vent hole on the new basin so when the oil poured out of the motor it pooled up and overflowed the sides. I was very upset about this needless to say. I mopped up the mess the best I could then covered the stain with dirt and leaves. I suspect it isn't even visible now. This time I vowed to be really careful. I didn't want a Valdez oil spill in front of the house. I had changed the oil in front of the house before with no issues but the Missouri disaster was still heavy on my mind. With cardboard down, an oil drip pan on that, a new Walmart oil basin, a check to make sure it was level and a double check that the vent cap was popped up, I pulled the plug. Perfect! Not a drop spilled.
Take your time, think things out beforehand and all should go well...most of the time.
