First AC test was a Grand Slam

Today my first AC test was a grand slam, it was 101 outside & inside never over 81 deg     , my cargo door is still uninsulated as are all the wall studs and 20% of the ceiling. The inside is mostly empty & I had myself, a big fan , tv and DVR running - that's about 150 watts worth of heat load all being cooled by 500 watt ac unit. With the trailer loaded & the other 50% insulation installed I should be able to keep interior at hopefully 70 deg.
