Has anyone removed/replaced/etc the roof SAE plug? I think I would like to replace the plug with a small RV roof solar plug and run wire and MC4 plugs instead of the SAE. Seems to MC4 would be a better suited connector for long term roof top use. I was hoping there's enough wire slack in the current setup to pull a few inches out to solder or use butt connectors or something.

I think my 2015 Fleet had the same SAE plug, which I replaced with an MC4: https://www.amazon.c...e?ie=UTF8&psc=1

Removing the SAE plug takes a little time to remove the caulk and (I think) caulk tape. FWC recommends WD-40 to loosen the caulk. The roof hole is barely wide enough for the connectors on the MC4 mount - trim about 1/8" of the hole on one side. You could also use the screw caps from the SAE mount, but I preferred the MC4 wire connectors. You can reuse only 1 hole from the SAE mount. Be sure

to caulk well.

That's a nice cover...I opted for just a cover only https://www.amazon.c...0?ie=UTF8&psc=1

...my plan was to spice into the stock wiring and run about an extra foot of wire through the cover via the gland nuts on the cover and then terminate the ends with MC4s. Glad to know there is a little wiggle room with the FWC wiring.

I used a GoPower entry plate with 10 ga. MC4 pigtail.  It is held in place with screws and 3M 4200.  Been on the camper since 2018 and no leaks.

I have a ATC bobcat on which I replaced the SAE with that same cutting edge housing that Jack used. There was not enough slack in the wire to do the job from the roof. I had to remove one of the ceiling wood strips inside and carefully slit the headliner so I could make the connections from inside. Then I pulled the headliner back together with double stick tape and reinstalled the wood strip.
