Hey Alex. From the information I can find online it does look like your 2011 Keystone Cougar 318SAB does come prepped for a second AC unit. The bedroom roof vent should be reinforced and pre-wired for a 13.5k or 15k BTU unit. To check if your trailer…

B and B Molders RV Access Doors for smart upgrades
Tackle utility pass-throughs and service panels with confidence using B and B Molders RV access doors. Choose between key-lock and thumb-lock styles, then measure your cutout to confirm fit and check rear clearance if a lock protrusion could be an issue. For weather protection, pair your install with butyl tape and non-sag sealant, and match the listed color to your finish.
They work well as pass-throughs when matched to the right size and sealed properly. Verify the opening is large enough for your cable or hose and that the door thickness suits repeated use. If you expect heavy abrasion, check that the door material meets your durability needs. For a clean install, confirm it feels solid and leak-resistant after sealing.
Choose a key lock if you want keyed security, or a thumb latch if you prefer quick, keyless access. Confirm whether you have clearance behind the panel since some locks protrude into the cavity. If security is critical, avoid light-duty latches and consider a keyed version. If a key model includes only one key, plan ahead for a spare from a locksmith.
Use butyl tape on the mounting flange and a non-sag sealant around the perimeter for a waterproof seal. Some kits include screws or putty; if not, have self-tapping screws and sealant on hand. Lay out the cut carefully, drill pilot holes, and deburr or file edges before mounting. Tighten evenly to help prevent leaks.
Measure your cutout and match it to the listed cutout size for the door. If your opening is close, be prepared to slightly expand the cutout. Check outside dimensions and mounting hole pattern if you want holes to line up. If there isn't an exact size and you don't want to modify the wall, consider having a shop source an exact match.
