Proper way to re seal camper walls

I used 4" wide eternabond tape for everything on the roof including gutters, front/rear roof seams. I used proflex on all other areas. I left the butyl and taped off so I had clean lines. Looks good and gives me piece of mind that it is better than factory and won't leak.

On mine the bathroom roof vent seal was leaking and the escape hatch vent also was starting to leak, I replaced all the butyl and resealed with self leveling sealant on the roof I used Dicor up there and geocel for the walls and seams. The biggest problem was getting the silicone cleaned up.

I don't want to tell you that you should do that, without seeing your camper, I just know mine was pretty neglected and I felt it was needed. The silicone was in bad shape and I know the butyl was starting to dry out. I am glad I changed all mine out making sure its a tight seal. Just one observation, at the RV parts place that I get my stuff, when you buy any parts that attach to the camper they give you enough butyl to seal it. I did my best to seal everything on my camper roof, sides, doors every thing except the windows. Ill get to them also for now I have just resealed them with geocel.

my dealer sealed everything with geocel before he even gave me the camper. he said he highly recommends this and it really does prevent problems down the road.

Northsore, so you think I should remove the butyl tape that is already there around the seams and the jacks and then apply new butyl tape and cover with geocel? I guess I am a bit apprehensive about doing more harm than good.

I just finished that project, I removed all the intrusions except the windows, and resealed the with the butyl and sealed with geocel. I did the electrical connection, water fill, sewer hose compartment, cable tv connector, stove vent, every thing except the windows.
Mine was coated with silicone over and over, so I might have went overboard but felt It needed to be done correctly.
