Run Slide off Truck Battery

[Loneeagle]

I have a 2007 Ford F150. My trailer is a Flagstaff MicroLite 30amp unit. Can I run the awning, slide, AC off the truck battery for Demo purposes for someone interested in buying the trailer?

Thanks,
Terry

I can on my camper.

But, if they're really buying it, aren't they going to need a good working battery for the tow home?

Thanks for your help.
The battery is good but low right now.

I really don't think so, your TV is only going to give you a trickle charge to your unit, Your going to need to have that units battery up to charge atleast. Or buy a 30 amp to 120 v plug that you can get enough juice with to your convertor so it will work. A/C will work off that way, but not from your TV battery. Make sure you have a rated 20 volt outlet when you do this and not a 15 amp outlet when you do that for the A/C. Remember the controls for the A/C are 12 Volt but the compressor is 120V at 17 amps. Did I understand your post correctly?

Agree with ependydad. I had battery problems on my 3 slide 5th wheel last year and when time to break camp, not enough juice to bring in slides or raise jacks. Conveyer wasn't keeping up either, but as soon as I plugged into my truck I was able to bring in slides and raise jacks.

You might try jumper cables direct from the truck battery to the trailer battery. You can get more volt/amps through than going through the inverter.

I, too, have a MicroLite. The trailer's battery operates only the stereo and ceiling lights. Hooking into my F-150 only adds the exterior lights. I have to plug into a 30 amp power source to run the AC, slide-out, electrical receptacles, and residential refrigerator that I installed. This forum advised me to purchase a 3500 watt generator to equate to shore power.

Thanks,

That's very helpful.

You are not going to run an A/C off your truck battery Your slides might work if you still have any juice in the batteries but as the OP asked AC. I don't care if you have an inverter for 12v to 120 volt it will not work off your TV alone. You can not get the amperage you need from your TV plug. So I agree with Hector517. Espendydad explain how you you could run a A/C off your Tow Vehicle battery? That is what the OP asked also?

Not true.

The battery also powers the bathroom fan, the furnace fan and igniter, the water pump, the water heater igniter, the fridge electronics and igniter, slideout motor and power tongue jack.

Thanks,

The main thing is to be able to demo the awning and slide. Possibly the AC just so they know it operates.

Appreciate your help.

FORGET THE A/C it will not work off 12 volt period. I don't care what anyone says. without an inverter and better be pretty big at that....

You're right, I missed the AC part and only saw the slides and whatnot.

I've read of a setup where you could do it, but it was a pretty specialized setup:

TV charge line, inverter, and running a fridge

This is impossible to answer without knowing the requirements of the fridge, and more importantly, the gauge of the wire from your TV alternator to the trailer.


I have a 3000 watt sine wave inverter with 4 6v batteries in the trailer and a 320 amp alternator in the truck. Also, I have a separate connection from the alternator to the trailer using heavy gauge welding cable, with a disconnect in the bed of the truck. I can run the 13,500 BTU bedroom A/C all day while driving. (kitties riding in the trailer)


The moral of the story is that you need a good (heavy gauge) connection from the alternator to the trailer batteries to ensure sufficient current flow while driving.

In my MicroLite, yes, the Fan-tastic fan operates off the battery. I haven't tried any igniter. I installed a household fridge that plugs into a receptacle. But, the slide-out definitely requires 30amp power.

X2 You can not run the AC unless connected to shore power.

Unless you have a fully charged 12V battery, it cannot be safely towed. In the event the trailer and tow vehicle become uncoupled while traveling, the battery is what will engage the trailer brake when the cable is pulled.

Witch Doctor has it right. 12V accessories will operate, including slide, IF enough amperage is coming from the TV. On my Expedition, the trailer doesn't get 12V to the battery unless the ignition is on. Having the TV Running during test will both provide extra amps AND insure 12V ťo the trailer battery through the 7pin plug.

Regardless,AC isnt going to work without the 120V connection.

When trailers are delivered to dealers, they do not come with batteries. The transporter runs out the slides using the TV battery for check in. You could run the other 12 volt stuff the same way, but if you really want to show the trailer for sale, you will need a 120 volt power supply.

Good luck selling your unit.

You've never used the furnace or the water heater on propane?
Both require 12v battery power to ignite the propane.

The slideout does NOT need 30 amp AC power.
It uses 12v DC battery power.

And do you mean you had a residential fridge installed, instead of the 2-way stock fridge?

The 4 transporters that I worked with all had their own batteries that they installed/removed from my fifth wheel when they picked it up/dropped it off.

A battery is required for any trailer that has brakes so that the emergency breakaway works.
