Caleb and Andrew,
Thanks for the info. Doing some quick measurements, I think I can fit into a Storm 2720 but need to look into it more. I'm not yet invested in a pro-battery system and don't plan on it anytime soon. Most other accessories will probably travel in my Lowepro Photo backpack, so it would just be sled and maybe arm.
Thanks for the reminder on desiccant containers. I'm traveling to India in January and those will be a must then.
Cheers,
LL
