first, the furnace doesn't need a generator nor shore power to run. it uses 12v battery power. you will need a generator or shore power to re-charge the battery.
furnaces are the main battery drain on a trailer. one nite of constant furnace usage will completely drain one battery.
that's why most of us that dry camp, go with a two battery setup.
second, the a/c will require a generator or shore power to run.
the general consensus is that something like the Yamaha 2400, would be the minimum needed for a Dometic 13.5 a/c.
and if you camp at altitude, you need more power to run the a/c.
i've been able to run my Roo's Dometic a/c, with my Honda 2000. but this is rare.
you can find other Chinese-made inverter generators, that have 2800w and above for under $900.
inverter generators are much quieter than cheaper open-framed contractor generators. most have decibel ratings between 53db-64db.
IMHO, the best setup is two Honda/Yamaha/Champion 2000w inverter generators.
all 3 brands have the ability to be paralleled with a matching pair, for 4000w, if needed for a/c.
if a/c isn't needed, you only need to take one to run everything else. they weigh about 50lbs. each.
