Battery boxes on tongue?

Our new to us 2005 Keystone Cougar 304BHS has a curved front and I am trying to add 4 GC2 6v batteries, but am having great difficulty finding options for battery boxes.

I'm guessing you've already purchased these batteries :@ , otherwise I'd have suggested you not put big $$$ into an expensive box like a Torklift in order to accommodate a gaggle of flooded batts but instead put those $$$ into AGM batts that could be mounted anywhere, in any configuration - Perhaps a couple on the tongue in conventional battery boxes and a couple more in the front pass through storage compartment. Easy to do with AGMs. ;)
