Thank you for all of the good info my friends! I will look into the Diehards and see if my brother can get them. He owns a battery shop so my choices are plenty.
I am not necessarily going to try to get to a true 100% while out camping and I don't think that will be a huge burden on the batteries with it only happening a few times a year. When I return home I think the boondocker should charge them to 100% just fine.
I mainly want to get a fast charge 1-3hrs and get the bulk of my amp hours back. Then when I hit the road every few days I can let the generator run for a bit longer to try and get closer to 100%.
Now the boondocker is looking attractive but the Schumaker would be less $$$ and portable. My magnatek does just fine except for charging. Maybe I should unhook the charger end of the magnatek and rely on the Schumaker.
Ooh Jeez I am really confused now, I hate too many choices!
