Advice on installing Eternabond 4" strips?
About 30% of the seam has separated between the extruded aluminum gutter and the flimsy fiberglass roof material on my 08 Itasca 30B. Last year, I recalked several feet of the same seam using Geoce...

I know all I'd do is clean off the old caulking, put a thin bead of new caulking in the groove, and try not to spread it out to much. Wipe the upper edge of the gutter with a solvent. Let the caulking dry, then attach the 4" eternabond to the upper edge (what is that, 1/4" or so) of the gutter, hopefully with some help.
Then gently lay the EB over the new caulking. If it makes a gap on the front and rear, I'd figure that out later.
So what you'd end up with is a eternabond slope over the two 90° angles a bit. Like at 45°. That stuff sticks incredibly well and once it's stuck to the upper edge of the rain gutter (channeling water into it directly from the roof), and to the roof, no more leaks.
As I said, the only worry then would be the gap at the front of the roof and the rear. EB is strong enough to bridge a small gap without sagging to much.
Hmmm. Thinking about that. Maybe a small wedge of aluminum angle block stock cut like 1/2" long and stuck in there before you lay the tape...then the tape and caulking would hold it in place and prevent water intrusion. Wouldn't take much, all you'd worry about is wind driven rain getting in between the top of the gutter piece and under the EB. If you're not driving in the rain, and you're not in to many wind/rain storms, you'd be fine for years.
IMO.
