Thanks everyone,
A 105 or 115Ah deep cycle would be nice, but then Im lookn upwards to $300.
I think It'll satisfy all my needs(laptop, cameras, other) but its a heavy bugger, and pricey.
I already have a 1900Ah jumpstart for the mount from supercheap.
Guess i better do some solid reading, and find out what my requirements are, and what I'll need plus chargers.
