Have no idea what I'm doing-help!

We bought a camper 2 months ago to live in (family of 6 plus a german shepherd, yes we are insane) while we build our house. Silly us, we know nothing about campers (but are learning). It's a bumper pull 34 ft.
One thing we didn't realize is the fact that the a/c only gets it down to 85 in here during the day. And honestly, it doesn't blow well and the air isn't too cool. I'm most worried about my poor dog-he's dying in here. Next week temps go up to 105-110. We are in arkansas.
We live in my brother's back yard and had an electrician hook up a 30amp thingie which we are plugged to.
The heat got so intense we bought a 5,000btu window unit and installed it in our bedroom. It's plugged into a wall outlet in the camper. It says it draws 6amps and our roof unit draws 15 and we have a total max draw of 30. We actually thought about getting another 5,000 btu for the front and not use the roof unit at all since this window unit really works well.
BACK to the point now, the breaker keeps tripping. But only at the hottest part of the day. At night we can run both, have 2 tvs and the playstation on, and even run the microwave without it tripping. But during the day even with everything off and the fridge on propane, the breaker trips repeatedly. My brother has also complained of dimming lights in his house.
So...what do I do and what could be wrong?

    How old is this travel trailer? If the A/C coils haven't been cleaned, you may be able to get some relief if you so. Up on top, the plastic shroud comes off. There'll be a fan blade facing the front of a coil at the back end of the unit. Hose that one out. Then the sheet metal that forms the nose of the A/C comes off and you clean it. More carefully since you can get water down into the trailer. You can also clean the condensate drain pan and be sure its two outlets are open so that water drains out onto the trailer roof.
  • Check the voltage during the hottest part of the day the voltage could be dropping. If it very hot all your neighbors are also drawing a lot of power also. As you know as the voltage goes down, then the amperes go up.
  • 30 amps means you have maybe 25 amps total.
    15 for the roof AC
    7 each for the refer and water heater. Your overloaded. Make sure your water heater and refer are manually forced to gas run a heavy duty extension cord for the window AC. You should be OK. BTW, typical roof top AC is lucky to cool an RV down to about 15 degrees below outside temps.
  • That's an idea which would work for now.
    We are pouring a separate slap on our land and having hookups placed out there so we can live on site during the build. Would it be possible to have a normal household outlet in addition to the 30 amp on the same pole or whatever?

    X2, and get your shepherd shaved!
