We have had a 2009 Freedom Deluxe for a little under a year now and I am trying to install a solar panel charging system with the help of my son. 

I think I am going to go with two 6v deep cycle batteries, probably from Interstate but I am wondering about where to locate them.  I originally though to extend out the rear bumper and mount them there since it was closer to the original location but am not real happy with the idea of having the extra weight on the tail end. 

I am now considering mounting them on the tongue to get a little more weight on it to offset the water in the tank and resultant sway and I have noticed a couple of installations with an additional battery mounted in front of the tanks. 

 

I have looked at the shelf unit from Little House Customs but have some reservations because I have not seen any set-ups that have the batteries mounted above the propane tanks and am wondering if there is a reason for this?  Is it dangerous?  What about a custom shelf mounting the batteries below and the tanks above? 

 

What else might preclude mounting them on the tongue? Security? Too much weight (about 120lbs total)?  What am I overlooking? 

 

Thanks,

 

John

I'm getting ready to add two batteries on the rear of my 17' LD.  I think I have added enough weight on the tongue with generator and enclosed propane set up and the electric jack to offset most of the extra weight on the rear of the camper.  I plan on putting them in an aluminum under body storage system used on semi trucks or if that doesn't work will have to fabricate a custom storage box.

Although 12V, an AGM battery, which does not need to be isolated, can be installed anywhere inside the Casita. Just a thought.

I have the OMW over the tanks platform on my 16er. While I don’t have batteries mounted there, I do have a Honda generator that lives there al the time. That additional weight on the tongue made a huge difference in the way the trailer tows. No more sway issues and I can now travel with a full fresh water tank. I’m thinking installing the batteries out front would have much the same effect. I would think mounting those batteries on the rear might result in making the tongue weight issues our trailers have even worse.

be sure to weigh your trailer & tongue before adding significant weight to either tongue or rear and again after you've made your changes. there is a scale on here somewhere (can't find it now when i need it, of course) that gives general guidelines, such as for every lb you add to the rear of a 13ft PD, subtract 6 lbs from the tongue weight, etc. it's really important that your trailer is loaded the way you normally travel (full fresh water tank vs empty one, etc) at weigh-in. make sure the total trailer weight does not exceed the 3500lb axle rating (some folks have in the past which leads to bearing/tire/axle failure) and that your tongue weight is within 10-15% of your trailer weight for maximum towing stability.

    good luck with your project and safe travels.............

We met a nice sigle lady at the Marble Canyon camsite north of the Grand Canyon. She installed her second battery under the bed at the back of the trailer. he also installed a full time solar panel to the roof. She preferred "boondocking" to save money and that she never needs electric except to run the a/c.
