I am sure this question has been asked and also answered on this site but I cannot seem to find it.  I am wondering if I am able to trickle charge my 13 RP 172 while towing from my 12 Jeep Grand Cherokee?  I am using the 5 pin plug and we are planning an extended vacation in the coming weeks.  Again thanks in advance to any response, this site is awesome for us "new campers".

Are you sure it's a 5-pin plug? If so, then there is no charge line and therefore your trailer won't charge. You need to use a 7-pin plug to get the charge line.

The 5 pin wiring spec does not provide a 12v feed to the trailer.

EDIT..

Are you sure you have a 5 pin.. I really can't imagine a new truck not having either 4 pin or 7 pin, usually both. (all of mine have since the late 90's)

EDIT AGAIN... Jeep says if you have a tow package, you have a 4 and 7 pin. The Pod has a 7 pin..

In fact, now that I think about it... the 5-pin plug doesn't even have a brake line. What brake controller are you using and how is it connected to the trailer?

I will have to double check when I get home.  But from what you are saying, if it is the 4 and 7 and I am using the 7 then it should charge the Pod as I am in transit?

Are you guys saying that with a 7 pin plug you do get a trickle charge or may be capable of modifying something to get it?  I don't think I do on my 10' F-150.  It would be nice if this is possible and an easy fix/solution.

If you have a 7-pin connector and it's properly setup, then it will charge the pod. The rate of charge is entirely dependent on your car's setup. In my case it's like the pod battery and the car battery are connected, so they charge together (fairly quickly). It's more than what I would call a "trickle". When my car is running and I plug in the pod after a long trip I can hear the engine tone change, so it's definitely putting a load on the alternator.

Maybe.

The charge line must be connected (and fused) to your vehicle's battery.  This is often not the case with many manufacturer-installed trailer connectors and occasionally not the case with aftermarket installations.  A charge line is not necessary for safe use of the trailer, so some may skimp on it.

The wire from your vehicle's battery to the connector must be of sufficient gauge (I'd say at least 8ga) to carry enough power (its a fair distance and resistance in the wiew becomes a factor) to be of use.

The feedback on this site is awesome, thank you all.  I will go home and check the connector and see if their is a gauge coming from my car battery to the hitch.

Thanks again.

You can also test it with a multimeter across the upper right pin (charge) and the lower left pin (ground). It should be 12+ volts. Here's a diagram:
