15k AC Question

The new 15K in our trailer is drawing the same current the 13.5 did in out 13 y/o trailer - 12 amps. Any 15A outlet that is burdened with other things should be able to run it just fine.
Given the option, I would always get the 15K.

Hi,

A 13500 may reliably run from a 15 amp shore power supply.

A 15000 may NOT do the same.

It amounts to an 11% increase in capacity. Most folks won't notice a difference.

If a 13500 takes one hour to cool an RV down, the 15000 would take 54 minutes.

Our 15k pulls 13 amps. OP will be happy to have 15k in 90 degree weather.

Not that big a difference. A 15K will run just as easily off a 30A supply as the smaller AC.

We swapped out our 13.5 for a 15 shortly after we purchased our current camper. Ours is 30 amp and as long as we don't run all these at the same time, we don't have any problem.

Electric water heater
Air Conditioner
Microwave.

So, we run the water heater on gas all the time, and we've never had a problem running the air conditioner and microwave at the same time. But if we flip on electric on the water heater, and the water heater kicks on, it almost always pops the main breaker in the camper.

Same with an electric frying pan or an electric griddle. If Air and microwave are running, and we plug in one of these, it almost always pops. Considering we cook outside all the time, I usually run a separate normal 20 amp cord from the power post to the picnic table and never plug into the outlet on the side of the camper.

We upgraded from 13.5 to 15 when we bought our mh and everything works fine on 30.

Can't help with the trailer review...but a 15K A/C will work great with 30a service. ..you probably won't be able to run the air, the mircowave and a hair dryer all at the same time...

Good luck with you new rig.
