Use of only 30 amp service

Congratulations, and yes.

As you said, careful monitoring of your electrical use and you will have no problem. One thing that you do not want to forget about is your inverter/charger. If not set fairly low, the charger portion can use a lot of incoming power. Things like your power awning and front shades are probably 12 volt items. The microwave and your AC should able to both be run at the same time. Be sure to turn your hot water heater and refrigerator to LP. In a short time you will figure out what you can and cannot run together.

Yes. A/C, Fridge, and HW heater running together will probably use more an 30 amps, but that's why the HW heater can run either gas or electric.

I solved my coffee pot on time down to 5 minutes total for a 10-cup brewing. Then it pours up the brewed coffee into a thermos carafe. The thermo carafe keeps the coffee piping hot all day long so there is no power time required to keep it hot. We are bean coffee lovers so this Cuisinart Grind and Brew Coffee Maker Model DGB-600BC works just great for us.

325 watts fridge
1200 13500 btu air conditioner (but may draw up to 1900 watts)
1200 water heater on electric

2725 total You will be fine on a 30 amp and will have enough power to operate the converter, too.

Duty cycle on an absorption fridge is 2:3 so it is on 40 minutes of each hour.

Cycling on a ten gallon electric water heater is 15 minutes every four hours if no water is drawn off. Time to first cycle is about 90 minutes on electric.

In the time before I had a hybrid inverter/charger I would flip the water heater off before I cooked or used the coffee maker.

Easy, simple rule to follow - single AC and the water heater on gas. In cold heater substitute the AC (unless it's a heat pump) for a space heater.

I have a 30 amp connection in my storage garage. I can adjust the inverters for a 30 amp setting. I run the fridge but turn off the hot water tank and the compressor that keeps the air valves working (not needed while in storage).

I run one air unit (13,500 btu) and the house/chassis battery charger. We seem to use about 20-22 amps in this scenario.

So, on your Tiffin, you should do just fine if you watch your electric usage.

MM.

I am surprised it doesnt have power management.

I run both ACs routinely on 30A with it. It manages compressor starts.

Another tactic is to add a receptacle somewhere and run a separate power cord and plug it into the extra 15/20A recep at the pedestal.

Mine was convenient to place in the bed pedestal near the bathroom and DW uses it for her hair dryer on 30A.

Congrats and YES you will be fine on 30Amp. We turn hot water to gas and run only one AC at a time. Usually no problems as long as microwave/coffe pot/ hairdryer are not one at the same time. Worst case you trip a circuit breaker and then don't do that combo again.

I suggest you also monitor voltage - some parks can be very low an that can cause issues.

ENJOY!

The power management panel (digital that tells you what power you are using) will turn on the second A/C only if there is enough power and will turn it off if you pull to much from say a microwave. As pointed out above two A/C's can run just fine but the power management controller in your RV will control when the second A/C turns on to keep power levels manageable (it will wait a while to know you are done microwaving and to let the A/C compressor rest before starting it again). Don't be surprised though if you are running lots of other things that the second A/C shuts off or doesn't run as often.
