Thanks j-d that was great help I have resantly done the tune up and oil change I went with the 10w30 weight oil and yes that was a typo I am using my phone and it auto corrected liter sorry about that. I've come to find that I have the small block engine (360 5.9L) when I went to auto zone it came up as the dodge b300 for parts (please comment if I'm using the wrong parts ), I have to get a power steering pump and oil pan gasket as well as transmission filter and gasket.These are my next things I want to get too on this rv. then I only will have a brake issue and a windshield to get to be able to hit the road for our first road trip.Again thank you all for the great info
