Electric plug in bed??

Was not sure where to post this so I put it in here as I think the camping crew would be the ones to use this plug.
I have 06 dc and tow an 20' tent trailer. When I go on 4-5 day trips I lose the battery in the trailer. I want to know if I can hook up 2amp battery charger to the plug in the bed with the truck running go for a nice trail ride and come back to a charged battery?
How much power can you pull from this plug?

 

I would like to hear/ see what people have ran off the bed/plug? Lets see it guys.
I want idea of what I can run.

 

Dremel, Air Mattress air pump

 

yea, dremel and air mattress pump..

 

Aren't blow dryers around 1400 - 1600 watts? Amazing it didn't fry something, at least a fuse!

 

Actually you know what, I take that back. I had an extension cord coming down from the deck for that. Forgot about that... I looked on the blow dryer when I grabbed it, and I think it was 1600 watts, and I remember thinking "that won't work in the bed outlet!". It was to heat up some scratches on the door panel and work them out.

 

It's all good. I made a not-paying-attention posting boo-boo already this morning. Fecal matter occurs.

 

When our power was out one morning after a bad storm I tried letting the wife hook up the hair dryer to the bed outlet. It doesn't work for more than about 1 second. It won't fry anything. Toyota is good at building in safe guards for idiots that try and break their toys.

 

Then I should be able to run a 2amp trickle charger for my battery in the tent trailer. Cool

 

At 2 amps you are going to have have that thing hooked up for a long long time to charge any battery of any size.

You'd be better off doing a dual battery isolator for charging your 2nd battery

 

Does your truck have the factory tow package? Does the tent trailer use a 7-round trailer plug? If the answer to both of these questions is yes, then forget the plug in the bed and just plug the trailer connectors back in and start the truck. The Tacoma's with the factory tow package are designed to charge the RV batter system while they are connected to one another, and using the truck's alternator will be a lot faster than some kind of trickle charger.

Or your other best option would be to hit a camping world and pick up a solar trickle charger, and leave it connected for the whole 4-5 days. That should prevent the battery from going dead on you at all.

 

going off what maverick said, don't waste power going from DC to AC to DC (inverters are notoriously inefficient).

Run 12v from the alternator to the RV battery and ground it. Done.

 

Okay how about plugging in the factory plug for an aux. battery? So it can charge it while the vehicle is running.

 

Late on seeing this thread but yes you could but NO you would not get a decent enough charge on your battery. A deep cycle battery that starts to run low would take a full 12-24 hours to properlly top off with a 2amp charger. You're better off getting a small Honda 1000i generator and plugging it in for the day.

 

I took a electric chain saw on our last camping trip.. I ran it off the plug in the bed, but it barely enough power to cut through the dead aspen trees..
Hooked to a normal outlet it flies thru wood.
I did get enough cut to have campfires for a few nights. Saved me enough $$ to pay for the saw..
Not much juice there though..
