So this question is about a 72 Shasta remodel. I have scraped sanded picked and cussed getting all the sealant off the metal roof. It's beautiful and shiny now. Everybody is telling us we need to seal the top with something. If the metal is in good shape and doesnt leak and I seal all my vent holes why would I cover the whole roof with sealant again? This is my first roof issue I've dealt with and don't want to disregard advice but it just does not make sense to me.

I believe you are absolutely on the right track. The roof sheeting on the Shastas came from the factory with paint and matched the body color of the camper. Aluminum sheeting will not allow water to pass through and does not need any help to stay sealed. Some roofs were made up of multiple panels, and had seams in them. These seams may be found to leak moisture through, but certainly do not require coating the entire roof in order to seal them.
The only sealing that is required is where there are seams. The original sealant was putty tape, applied to the joints where the roof and walls meet, and any places where there are openings through the roof and walls, such as the vents. This putty will fail after a number of years and must be replaced at regular intervals. When properly maintained, there should be no problems with infiltration of water into the body of the trailer.

I agree. Don't coat the roof!
If the seams have gaps or dips, you might consider sealing them as neatly as possible. Either OSI gutter seal (Lowes) or paint on Proflex (not the caulk) will work. OSI is very clear and easy to smooth with a paint thinner dipped finger; you will barely notice it. Proflex is gooey, and a little messy, but works really well, but you will notice it. Since it is paint on, it's easier to reach across the roof compared to having to work every inch of the seam when using gutter seal. Both take at least two applications. I paint my roofs white after priming. If it is embossed, a roller works very well, or you can spray. The roller puts more paint on and seems to retain the shine.
The roof vents main seal is putty. I use Dicor self leveling lap sealant around each after installation. It is extra insurance, touch up-able and removable when repairs are needed. (not fun but possible)

Yes after sealing paint the top to give it a nice finished look and a lite color will help it reflect the summer heat.

I actually just saw my roof for the first time today. (Camper was found and delivered in the winter. It was actually delivered during a snow storm and I tarped the roof to protect it just in case - took it off today). It is sort of a rust color with some gray stuff around the j-rail and the vent. I posted some pics on Facebook to ask if it was a normal roof (don't laugh) and supposedly it js. It is a metal roof and I'd like to clean it up and paint it white if that's possible. It is made up of panels like mentioned above. And the roof will have to come off to replace the ceiling panels inside, right?
