low coolant / add water?
My coolant level is about 2 inches lower than the cold level, do I have to buy and add coolant even though I am not driving the RV right now ? ( its hooked up at an RV park ) Can I just add distille...

I found this link to a coolant type chart at Ford Parts. 2003 looks like the year that Ford switched from green coolant to yellow/gold coolant.

Has your rig had a coolant flush in the past? If so, the shop that did the flush may have not put the correct coolant back in. Maybe, maybe not. If you look at the chart you will notice that there were still some vehicles that were using the green coolant about midway through the manufacturing year of 2003, but it looks like Ford made the decision to move to yellow coolant across the entire product line. I doubt there were any mechanical changes done to accommodate for this. That would indicate some interchangeability between the coolant types, but as others have indicated the yellow has a longer lifespan than the green.
I would not mix green and yellow. If you felt like changing back to yellow, then fix your leak, flush your entire system, then refill with yellow.
