3M Marine Sealants for Campers
Having come from the boating world, is there a reason folks don't use the 4200/5200 marine sealants from 3M? They last years and are proven sealants. They can be tough to remove but isn't that the poi...

It was mentioned above that 5200 was hard to remove. I would say it is virtually impossible to remove without severely damaging whatever it is cured to. One time, on a boat, I needed to remove a failed through hull transducer. It actually had to be cut out. Somewhere I found a product that was supposed to dissolve 5200. It didn't.
I would caution against ever using 5200 on an RV unless whatever it was attached to can be easily removed and replaced because the 5200 definitely isn't.
