RV Repair: Seam Sealing, water seepage, silicone seal

Question
I have a 2003 Springdale 195 camper.  I purchased it knowing it had previous water damage.  I have removed the front interior wall due to some more water seepage.  Now that I have it apart I can see all the damage that has occurred.  It has some rot that I will correct now that I have it apart.  It appears that I have water coming in along the seams where the front and sides of the camper come together.   About half way up the front is where it seems to be leaking.  What is the best way to attack these seems?  Should I plan on removing the outside skin or is there a way to seal it from the inside out? If could be done from the inside I am not sure how, since the seam is behind the corner wall studs.
I am not sure what would be the best way to start on skin removal.  Does the rubber on the outside corner seams come out and then are there screws behind the rubber?  It appears the aluminum skin is stabled to the wall studs.
Any advice on how to attack all this would be very helpful.
Thanks


Answer
Hi Russ, Yes, there are screws under the vinyl pinch molding. The skin is stapled to the frame on the top side of each panel. Remove what you have to for access to make your repairs. Then reinstall and seal all the seems with a like colored silicone. Reseal the roof with rubber roof sealant. (not silicone.) Seal all gaps from the outside. Hope that helpful. Good Luck.
