the wire size and lenght is going to vary everytime
you can measure the voltage at the batteries and use that
for specfic calculations for that rv
it will mean a reduced charge in watts value and a decrease in efficency 'number' aka lower voltage at batteries than converter ~ (output watts devided by input watts)
when compared to the guide line numbers we have calculated
to calculate vdrop from converter to batteries you will have to know the resistance of the wire and the amps rate, and the vdrop will change as the batteries charge and the amps flow decreases
knowing whether the generator will even do the job is more important !
and what your Final voltage set point IS
dont get lost in trying to find data that doesn't affect the out come of selecting the right match between converter and generator
of course when in doubt Go Big on the generator
