Propane Quick Connect for 2026 Coleman Legacy 1905RB

Question:

Hello, I would like to add a propane quick-connect port to my RV, a 2026 Coleman Legacy 1905RB, so I can connect an exterior grill. I am attaching photos of my current propane setup under the RV.?There is an existing propane distribution tee with two copper lines already in use. I’m not sure if this part would work or what extra parts I would need to attach it. I will hire a professional to do this but I’d like to have the parts needed. Thank you very much for your assistance. I appreciate your guidance.

Hey Cynthia, thanks for the photo! The quick-disconnect like # 104052-MBS is what you want, but you’ll also need to tee into that line. We can’t confirm the exact size from the photo (usually 1/4" or 3/8") and even if we could we don't carry the right tee for that setup. Since you’re having it installed, I’d grab the quick-connect and let the installer supply the correct tee and fittings once they verify the line size.
