so how much moisture is in the air? more moisture, means it feels hotter.
are all of your vents open?
what's the btu output of your a/c unit and how large is your r.v.
how hot is it outside and what are your walls made with. aluminum sides and studs will transfer more heat than wood walls.
it does look like the unit is cooling some air, that's why i asked if all of the vents were open..
when i was in arizona. it took a 11,000 btu window unit and the 15,000 btu roof unit to lower the inside temp of a 32' trailer below 80'f. it was over 115'f outside, i had no shade over the r.v.
both a/c units were running on high. i could get colder air from the vents on low, but that resulted in less air getting cooled. so it was hotter with the a/c units on low.
ok, the difference between the two air conditioners. the higher btu unit can cool more air.
the larger btu unit uses a larger capacity compressor, evaporator and condenser. they may fit into the same sized a/c body as a lower btu unit. thus saving manufacturing cost.
just like the roof units all look the same from the outside.
