I should also add that I have approximately a 10 foot run of #8 wire
running from the batteries to the inside of the trailer, hoping I would
not have a significant voltage drop. This will terminate with a PP
distribution block. Total wire run should be less than 16 feet and
closer to 12 feet.

The issue from running direct to battery is voltage drop to your
KX100. You need 13.8v minimum to get full power out of the KX100. I
run my KX3 and 857D out of a class B Sprinter and have had to resort
to a power supply run from shore power (or my Honda 2KW) generator to
get really clean power at adequate voltage levels. I have a direct
line from my PP distribution block to my batteries, but the batteries
will not power either rig at full output power.

Greetings
I know this is a bit of topic but I this this list has the
expertise to give me good answers.
My station is a KX3-KXPA100 with a PX3. I have a quiet, to me, 30
amp switching power and a 2000 watt Honda generator that generates
some, but not objectionable noise. The NB on the KX3 clears that
up totally. I also have a 20 amp liner Astron power supply but it
is heavy, bulky for use in a small trailer. And, it may be light
for running an amp.
I course I do not need to run it at 100 watts, either.
I am trying to decide if it best to operate from the trailer's AC
or directly from the batteries.
And, if I use the batteries alone are there precautions I need to
take.
Of course, if available I would use "shore power". The AC from the
trailer seems to be adequate when running with or without "shore
power" or with my generator.
I guess my real concern is the issue of using DC directly, and
what should happen for protecton between my batteries and station.
