Looks like I will be adding a second battery to my 177SE. The current battery location is 2 inches too short for what I am looking at. Has anyone else run into this? I don't need any more tounge weight but anywhere else would likely need an AGM battery and I am not spending that kind of money.

The dealer ran into the same problem when they promised me that we could use to batteries, On our 177 SE. So I have decided to use one group 30 or 31 battery and install solar to the trailer. There are batteries that do not have off-gassing and could be mounted inside the trailer but most of them don't have good amp hour capacity. If you figure out something to solve this situation please post here for all of us to see. If anyone knows of a battery that would fit in the spot of a group 24 or 27 that has more amp hour capacity than the group 30 or 31 please share

Cut/grind off the existing bracket, and get a larger one welded up -

This picture above showing the battery boxes on top of the frame rails is obviously not a retro 177 SE. The 177 SE has much less space between the front of the trailer and the propane cover. The 177 SE trailers front curves up and outward towards the propane box and therefore the higher you raise the batteries on top of the frame rails the less room there is for batteries between the propane cover and the front of the trailer. Been there done that we tried everything. Thanks for your thoughts and posting.

Give it some more thought. There's no reason an extended battery bracket has to be mounted on top of the frame as in the picture, it could be welded to the bottom (or bolted on) and the batteries mounted on either side. I'd just run an extra angle (or channel) iron down the middle to make sure it could support the cantilevered weight.

Then, get fancy and put a toolbox in the middle.

Not a bad idea I'll have to do some checking for Dimensions and so forth, Thanks

I finished putting a WD Hitch on my 177se, and now that I know where that hardware is attached to the frame I will be making a dropped box in place of the current battery holder. it's going to hold two GC2 6Volt batteries side by side.

Where did you procure your battery box?
