Thanks everyone. It looks like we'll have to pick up a few more things. To answer the questions:
1. Probably 95% dry camping, occasionally shore powered.
2. Parallax Tower Components, model 7345
3. Yes, we have a generator.
4. 2 weeks
5. I think it's portable? I don't know how to tell. It does have a controller.
6. No
7. Stored at home.
8. We have a smart charger (6a/4a/2a), so from what I understand, we can set it to 6a and when the battery is charged, it will automatically switch to a 2a trickle charge. It's this one: http://www.canadiantire.ca/en/pdp/motomaster-eliminator-intelligent-battery-charger-6a-4a-2a-0111517p.html#.VafT-_mM6Yw
9. No
