Under the tub it'll be exposed to the elements - not a terrible thing - but it's hard to get to for maintenance, so choose a gel/agm battery (and, having chosen one of these, don't ever expect to be able to use it as a starter - you'll kill it).
Inside the tub, the best place would be over the wheel arch. I chose the right hand side, because I use it less than the left. Inside my battery box is an inverter, which powers a powerboard that has a battery charger, the Engel and a double 240V outlet on the rear of the box. The battery charger charges the battery while we're going and then the battery connects to the Engel and a 12V outlet for general use in the tub.
I want to re-do mine, make it a little larger, make it a little longer. I'm going to lose a small amount of tub space but that's no real problem for me.
I'll post photos when I've rebuilt it. All I've done for now is spend $20 on a sheet of 12mm ply and whacked something together. It needs to look a lot more professional.
