Eagle dual battery capability
We recently took delivery of our 2013 284BHS. One of the standard features of the Eagle TT's, is the ability to have twin batteries. What they don't tell you, is the front battery on the front A frame can't be a group 27 or larger battery. Anything larger than a group 24 box won't fit. You can see how the battery box mounting rails are tapered at the front making it too narrow in the front for anything longer than a group 24 box.
When I worked as a parts guy at a RV dealer, I found out that a extra HD group 31 battery would fit into a group 27 battery box. As far as I'm concerned, it's the best way to go if you think you might go rustic (no hook-ups) sometime. But the front battery position on my Eagle wouldn't accept a group 27 battery box. So I figured if it wouldn't fit, I'd make it fit. So I cut the right and left side pieces and added a new front part that would accommodate a group 27 box.
As you can see, I have secured both my rather expensive batteries with a pair of BD Battery lock bars. And yes getting both of them on there took quite a bit of head scratching and wrestling with them.
