Changing Battery, Spark Plugs and Exhaust manifold gasket on my Ford Jayco RV

This is a video I recorded some time back where I talk about some work I did to change the battery and exhaust manifold gasket on my Ford Jayco RV

Nice seeing how you take care of the issues that pop up while you fix it up. Good to learn how to do these things and how a noise like that could be from misfiring spark plugs. Didn't even know there was something like a rust to primer paint.
