Pretty hard to answer your question without knowing the year of your TM.
A picture of the current calking would be helpful.
If your old calking is pulling away from the roof or vent... ya, by all means, remove the vent and clean the old calking. These razor blades make the job EZ without scratching the roof.

Replace the old butyl tape and reinstall the vent.

Then lay down a thick layer of Dicor lap sealant. This stuff is self-leveling. Don't worry about making it pretty when you lay it down because it will flow into a nice uniform contour as it sets.

If the old calking is just cracked, move on to scrubbing the area to be sealed with rubbing alcohol then apply the Dicor lap sealant above. No need to remove old calking that is still tight to the surface that it's applied to.
NOTE******* Never try to use ANY calking compound over silicone calking.
