About a 20 degree drop from outside ambient temperature is all you can expect
In the HVAC industry we don't measure the split from outside temps. The temp. is taken at the fresh air return (where it goes in) and then at the register. You should have an 18F to 20F split for optimal performance.
While my 27' 5er is new (probable operating a maximum effiecency)with dark tint thermal pane windows and the heavier insulation in the floor, roof and walls that Northwood Mfg. is known for...two weeks ago it was 110F here in Sacramento and my trailer maintained a constant 76F inside (with the shades closed and parked in the shade)....although it did cycle often througout the afternoon.
