the photo by dbir is typical. Two pieces of angle iron form a bottom and sides that the battery box sits in, the strap holds the box in place and the lid on the box. Some have the box bolted to the angle iron. I prefer strapped because I remove the whole battery box for storage in the garage.

You want about 10% of your trailer weight on the hitch, putting the heavy battery on the tongue helps in getting that desired weight distribution. Often water tanks and rear storage inside and outside on bumper can leave the camper tail heavy, which makes them prone to getting sway. Propane and battery put heavy in a good location.

Blasted things are heavy! I don't want to fiddle with trying to lower them into some under seat or slide them into cabinet storage. Drop that puppy on the tongue, connect it, strap it and done. If I do drop the battery outsdie.... hopefully it misses my foot. But it won't be smashing up the camper or spilling acid on stuff.

For a portable solar rig as others have mentioned it seems like it would be easier to hook up. My Scamp did not have one, or a place for one. As built it got power only from the TV.

There are batteries that are supposed to allow for inside installation, more money.

Yup people do!

My solar controller for the Scamp is weather proof and mounted in a small box mounted to the side of the battery box - but I use a portable system so the small box is left partly open when solar is connected. Even when the panel is not connected the solar controller remains on and connected to the battery and it seems to have done fine in that little box for six + years.

On my new SOB trailer the solar controller is also weather proof & permanently attached to 2 - 6V batteries inside a metal battery box with lots of ventilation.

Remote temp probes should always be used with the solar controller for longevity. This is because the required voltage for bulk absorption and float vary with temperature.

Do NOT put the charge controller in with the batteries! The gas from the battery(s) is extremely corrosive and will destroy the charge controller.
You also highly increase the risk of a horrible acid splashing explosion should a component spectacularly fail in the controller. Which is not at all uncommon.

Unless you have AGM or lithium, then throw it right in there and don't worry about it.
That said, lithium batteries should be inside the coach for multiple reasons.

Thanks for the info. Will have to contact the pro in California who did the new set up/install on my SOB the week prior to my picking it up to see why he felt it to be fine in that location.

FWIW, I would not and WILL not keep a "car" battery (wet cell) inside my camper.

Darral, that's a good photo showing a nice simple installation!

Yep, which is why I said "portable". My panels are in my camper right now, because I decided to go into town for a few hours. Otherwise they're just set up on the ground outside my camper. Very easy to walk off with.

I do a lot of hiking straight from my campsite (one of the benefits of camping way out in the mountains/desert) and when I do that I usually leave them set up. My truck is still there so unless someone comes in to my camp and knocks on the door, they don't know I'm not there. But if I drive my truck somewhere and it's obvious that I'm not around, I pack them up.

I have a group 31 in a boat battery box mounted on the tongue. The solar controller is housed inside a weatherproof switch cover I found at big orange. I like the way the battery box handle acts as a roof over the controller.

I like it on the tongue because I find that I need the weight there, and very much prefer it to be outside. My UHaul has the battery inside, and if I were to keep the trailer I'd remedy that.
