Well, again, thank you for your replies and support.
There had been few small areas where the roof WAS leaking. The previous owner informed me that during the last winter, some water had found its way in to a few small sealant cracks. When it got cold, the water froze and spread the cracks open. When the winter had ended, the ice melted and continued its way into the MH. It has not leaked since then. What I am now assuming is that those cracks had closed back again ( not spread open from the ice ) and now that it is Sept and the temps are going to fall again, I want this fixed to prevent any further water penetration. The damage had been minor and it is an easy fix NOW, I want to stop it in its tracks to prevent additional damage.
The guy at the local RV shop climbed up and looked at the roof for me, he suggested that I get a gallon of liquid roof to seal the cracks around the edges. Being the way that I am, I wanted to do the whole roof for peace of mind ( do it once and do it right ). So I ordered the 5 gal of LR and the AC gasket. Since I am doing that much, I should just go all the way and replace the fridge vent and the plumbing vent covers too.
Its old but, its in great condition. Since I got a good deal on it, I figured I could throw a few dollars into it to preserve it.
If your interested in seeing what Im working with, here is a link to the pictures and there is one picture of the roof
