How long should caulking hold up before redoing it?

On the roof I've switched over to Eternabond tape wherever I could. Do it right the first time and don't worry about it again.

Yep I did the same for my entire roof back in early 2008 and haven't had to touch it since except for the caulking along the front edge of the Eternabond on the front cap to keep it from lifting due to constant wind when traveling. Same went for all the seams and screw heads on the slide out and along the bottom faring of the sides of the trailer.
