Looking to reseal the trim, and vent on our 2016 Jayco 10SD. We had some water in there last year, not sure yet where it's coming from as I haven't investigated as we only found it prior to winter but it's pooling on the cabinet by the door.

At what point do you pull the trim off and put new butyl tape underneath (or something else?) or never have to do that, or can I just make a nice clean edge and seal it Proflex sealant?

For the vent, I'm assuming just scrap off the existing dicor product, clean it up and reapply with the self leveling stuff.

Being a 2016 and having a prior leak, I would remove the trim and reseal the edges. Butyl is good and there are other tapes available made for corners. Many folks would use Eternabond for the job.

Scraping old sealant from around the vent is not recommended. It's too easy to cut the lining. Do a thorough clean on what's there and put the new sealant right over it. All the name brand sealants work well.
 
If I suspected the roof vent had a leak I would remove the old sealant, remove the vent so I could check for any cracks in the flange. Sealant doesn’t last for ever and eventually does need to be replaced. You will also need to scrape off the old butyl and put down new. A warm day to soften the sealant and a plastic putty knife and carefully get it all off. You can call Jayco to find out what your roof is made of and what type of dicor they recommed to use on it. For the edges you could use eternabond or run a bead of dicor. First you need to find out where the leaking is coming from. If the vent’s not where the leak is, then I wouldn’t mess with it’s sealant.

Check under your AC unit roof frame for mounting screw roof membrane damage! My unit had two AC frame mounting screws digging into the roof membrane causing water to run down and out the vent opening into the camper! I had to bend the frame and screws up 1 inch and patch the damage. Came from the factory that way.
 
This column helped us find a good reroofer in TriCities area, WA. The same company has many in the east coast but this is the only one on the west coast. Our regular RV repairman had noted that we would need a new roof in 2 or 3 years. We didn't hesitate. Well we had seen some leakage and went immediately and had a new roof with a life time guarantee for 7000 dollars. What did they find? The leakage was around the AC unit on top and the boards were all bad there. We had all new boards and then a new roof put on. What a wonderful thing to sit in the rain and know we don't have to reseal up there anymore and the roof is majorally awesome. We should have done that when we bought the RV! 2011, 26 . The water had run under the membrane to multiple areas. A real benefit too was the added warmth of the home. We don't live in it all winter but we keep it at 40 degrees unless occupied and also use antifreeze, because we use the home for a guest house, when the children all come home. This winter we only used 1.5 RV tanks of propane and the heater didn't come on very often like in years past. I expect it makes things cooler in the summer as well. RV Roof Repair in Washington | Travelers Destination RV Service Center Flex Armour is the company.
 
Removing old Dicor is easier with a hair dryer, not a heat gun which is way to hot! Once warm, use a dull plastic putty knife. Use care because the rubber roof and even the aluminum roofs are very tender. When I removed Dicor off my roof I found rusty screws and one hole with no screw. I went with Etearnabond on all my seams, skylights, antenna, vents and plumbing vents. I also used it to secure solar wires on the roof to keep them from flapping and over the solar panel screws.

How many times can you put dicor lap sealant on top of dicor lap sealant? Would seem like eventually you'll have to scrap it off?

The corner trim is 1" wide, is 3/4" butyl tape wide enough or should I grab 1" and trim the excess off? I'm assuming once I screw back on the pressure will force it the rest of the way out? And I'm assuming use two pieces one on the side wall and one on the roof?

I'm kinda following what this guy does with his corner trim at the 10:33 marker.
