We spent 10 days in Utah last Fall
, late September - early October.
I can't imagine and would not go camping in that heat without A/C
It may cool at night but the days are hot. Take in mind that we are from Northern Wisconsin so temps in the 80's are HOT to us.
In the six years of owning a FGRV we have used the A/C far more than the furnace
. I often wonder when people say they live in XXXX
and say they don't need a furnace
or A/C. We own a "Travel Trailer "
and the climate across the US and Canada varies too much to say you will never use a furnace
or an A/C. I agree with others ,if you have to remove the A/C , then hang on to the it and see how it goes. You may discover that a skylight was not the best decision.
