You won't have much luck charging your battery off the BAT CHG plug of the Generator. This only gives around 8AMPs of DC current and is an unregulated source of 12VDC. There is only enough power here to give you a good trickle charge to your trailer battery. You will get behind the charge curve in a hurry...

You best way to charge your battery is connect the trailer 30AMP Shore power cable directly to the generator 120VAC receptacle using a RV30A-15A long 'DOGBONE' type adapter. You can get one of these from WALMART very cheap.

Your 2KW Generator will operate the on-board converter/charger and if it is a smart mode charger it will re-charge your trailer battery in a three hour generator run time.

If you do not have a smart mode converter unit then I would think your best thing to would be pick up a smart mode converter/charger unit for the trailer. You can also just pick up a smart mode portable battery charger like the B&D VEC1093DBD 40AMP charger and plug that into your generator and it will re-charge your batteries to their 90% charge state in a three hour time frame.

We camp almost entirely off the power grid in our OFF-ROAD POPUP and this is our game plan. We have a smart mode PD9260C converter/charger unit, added batteries, bigger battery cables, changed out ceiling lights to LED lights and this allows us to do almost anything we do at electric sites except run the air conditioner. We have it planned out to run what 120VAC items we want to run from an 600WATT PSW Inverter and 12VDC items from direct connected to the battery and can make it through one day/night run off our 255AHs capacity battery bank. Then at 8AM the next morning when allowed to run our generator we will connect the shore power cables directly to the generator receptacle using the RV30A-15A Adapter and then re-charge our 255AH battery bank back up to their 90% charge state so we can do all of this all over again the day/night run off the batteries.

When the generator is running we make our grind and brew bean coffee supply for the day and can also run some other 120VAC items we want to do.

In the evening we watch HDTV, play DVD, run 120VAC fans and lights, charge computers and cell phones, run our outside patio lights and lamp post light, and like I said do almost everything we do at a regular electric campground.

It does take some planning but we have been doing style of camping off the power grid since around 2009 in our OFF-ROAD POPUP.

This is the way we do it haha...

My generator is a Honda 2KW EU20001 which sits secured in the tailgate corner of my F150 truck covered and lockable bed... When we need to run the generator we just pull it out onto the tail and fire it up... The 30AMP shore power cable is long enough to plug into the generator from there.

Only way to camp for us...

howdy all
We recently bought a 19rd too and so far loving it. We plan on dry camping alot also so have been looking into ways of providing cooling without powering up our A/C.

Just yesterday in fact I found this video...


basically described: the guy makes an A/C from ice in a cooler using a small fan and some directed venting (I plan to use my 12v endless breeze fan). I wont be cutting into the top of my cooler, instead I will make an insert using plywood or rigid foam insulation to hold the fan & vent (still want to use the cooler at the lake/beach/etc). I haven't tried it out yet, but it looks promising!

This same video poster also has some neato ideas for heating up small spaces too. I've subscribed to his channel.

They have been doing this on SW golf courses for years. The ice box/fans are built into the golf carts. Works great in dry climates. Think it would be a disaster in humidity. It does require a quite a bit of ice.

Oh, ya, hadn't thought about that humidity aspect yet. I may try it out anyway during a hot dry day when we don't have hookups. I don't mind trying it out since we do plan to make our way out SW eventually and it will be nice to have lots of tricks up our sleeves.

The main thing I was interested in was the very low low energy cost of that 12v endless fan blowing cool air directly on us. I can buy a LOT of ice for the price of two 2000w Honda generators. (or I may just freeze water bottles in camper freezer - can recycle water better that way)

Would this work with dry ice, or would that just disappear too fast to be an effective solution?

I thought I read that dry ice releases a gas that is harmful when inhaled, so I think that's a no no.

I am thinking of using bottled water, that way it can be refrozen easily. So if we start with a "dry" ice chest filled with frozen bottles, as hot humid air enters the cooler it would condense on the water bottles right and then collect inside the cooler? Wouldn't we be actually removing H2O from the air more than putting more H2O into it?

I am going shopping tomorrow for the new cooler and will be looking into the right size bottles too so they can stand upright in the cooler. I plan to create a grid of them so the air is forced to weave itself in and around the bottles before it exits the vent. I must try this experiment! I have to know!

2) "We have also discovered that our new Yamaha 2000 doesn't work for the Jayco" - What does that mean exactly? The Yamaha 2000 is rated to 16.7 Amps, which is probably very very close to the peak amperage of starting your AC. Starting the AC in combination with anything else, such as the refrigerator or the battery charger will probably result in over-taxing the unit and set the circuit breaker. Is that what is happening? It should work just fine with everything except AC.. Or maybe not with the microwave and battery charger.
I've found that if I get the fan only running first, let it run a min, then click to AC real fast it will then start the compressor. Make sure everything else is off including all lights. Once it starts then you can turn on lights. We changed out to all led lights on our 2012 and that helps lots. Our new 2015 came with LED lights.

We have an older Yamaha 2400is [lots of construction hours logged],and your method of running the fan only first for a least a minute works for us.I leave the fan speed for the A/C on the lower setting after it fires up.
This forum has lots of great tips and general info.
