Adventure Trailer A/C Mods

Today’s Project was to make a few mods to my A/C system on my Adventure Trailer, I started by adding an insulated air in line and an insulated return air line. On the return air line I installed a 110v in-line fan pulling air from inside the tent. Next I built a divergent duct from 4” to 6” and connected it to the in-line fan and attached to the front of the A/C. After turning it on to test it after 15 minutes the tent was about 69 degrees and the outside temp was 84-86 roughly. After an hour the tent was down to 64 and the A/C was cycling like it should. Now to test it during the heat of the day tomorrow.
