My new travel trailer has 50 amp service and two air conditioners. When running both air conditioners the draw is 43 Amps does that mean I’m almost maxed out??

It depends. If they are both on the same leg, yes, but they should be on opposite legs of the 50 amp 120V/240V connection. A 50 amp RV service has 2 50 amp legs, for a total of 100 amps. If the loads are equally divided between the legs, you can actually draw 100 amps from a 50 amp service. Somewhat confusing, but that is the way it is...

50 amps units actually have two 50 amp circuits so in reality you have 100 amps of current split across two separate circuits in you RV. I would guess each AC unit is on a separate circuit in your RV. If you truly have a 50 amp hookup to your camper then you will not have a problem.

And that 43 amps is probably on start-up.

What is telling you 43 amps?

The The two air conditioners are on one leg does that mean the other appliances are on the other leg?

Are you certain they are on one leg? That would be silly to say the least.

It means that the manufacturer just didn’t care. You will have to do the checking to see what each breaker is connected to.

If both ac’s are on one leg and everything else is on the other you should be ok as long as you’re plugged into a 50 amp post. The question I have is what happens when you’re limited to 30.

Having two AC's on one leg is not so uncommon. I know on my 96 Vogue(not a cheap rig in its day) the main breaker panel is divided into loads that operate on the inverter and loads that don't operate on the inverter. This configuration may be more common in motorhomes than other rvs.
