An adjustable wrench, oil filter wrench, plastic dish pan, Funnel, plastic gas can, 4x8 tarp, and disposal rags are the needed tools. Buy oil at Advance auto store and they have tanks for the old used oil. Ask them where it is possible to change the oil.
Spread the tarp under the motorhome. Slide under with the dish pan and oil filter wrench, adjustable wrench, oil filter and disposal rag. Drain oil and change filters. Slide out with old oil, filter and tools.
Using funnel pour old oil into plastic gas can and clean dish pan. Using funnel fill engine with new oil. Remove tarp from under motorhome. Clean all tools and store. It's a ten to fifteen minute job. Deliver old oil to Advance auto parts store and pour into their disposal tank. Thank them. :)
