One of the best mods going is to add a Fantastic Fan to your trailer if you don't have one.
The last two I have put in have been Fan-Tastic 802251 RV Roof Vent which has the reverse mode and the thermostat. I like to set the thermostat at night and have it go off when it cools down.
Note: Scamp 13's you can't just replace the roof vent as it is not a standard 14" RV Vent you have to cut an additional vent hole in the roof.
This is the vent that was on my trailer, note all the added silicone sealer. If a vent or window is leaking, you should pull the vent or window and reinstall or replace it properly with butyl tape. A properly done vent or window install with butyl tape won't have any issues for years to come and you won't see any visible sealant mess. If for some reason you feel you need to add sealer on fiberglass use 3M Marine Adhesive Sealant 5200 Fast Cure White, 06535, 1 oz tube (Pack of 1) . Two reasons, silicone sealer won't properly seal on fiberglass and it leaves a horrendous mess for someone to have to clean up later.
Inside after pulling the original vent trim ring. Escape's are pre-wired for fantastic fans which you can see the wires hanging down. If your vent opening is not pre-wired you'll need to fish the wiring from wherever works best.
Vent removed and is setup with screws into wood reinforcements between the roof panels

Placed Colormetrics Gray Putty Tape / Butyl Tape 1/8" x 1" x 30' (Single Roll) strips around opening, set vent with screws, exterior is complete.
Cut the trim to correct depth, wired the fan, screwed the trim on and fantastic fan is done.
With the fall weather upon us, can't wait to fire this up in the campground....
