Kevin,
Going back to your original questions. I too have those in my Momentum. Great batteries and very heavy. For mounting/acid control i used dog food bins from Petco. I mounted them directly to a wall using sheet metal screws near the top of the bin to keep them from tilting since we do a ton of boondocking down some bumpy roads. Have not had any issues with them.
Like stated before on solar, if your charge controller cant handle the extra panel then there is not much of a benefit to another panel. 160 panels should be ok as long as you arent trying to dry camp with your fridge and a ton of stuff running. I would use one of the online Amp/watt useage worksheets to balance your solar if you are lookin toward that.
that being said, my batteries are fantastic. I like them alot. Oh and yes they do make boxes for these but good luck finding a spot to fit it :) they use these batteries in heavy equipment and cellular back up systems so they are pretty heavy duty. good luck/ Split
