As everyone knows, we have limited space in our battery compartment. So, what is the best battery to install. Some folks say two six volt instead, but it won't fit.
Some have an outside compartment wired in as an alternate - Torklift has a add-on compartment, for one. But I'd prefer one battery inside the stock compartment ... just looking for the best deep cycle, and want quality not necessarily save a buck.
We do boon-dock sometimes, but not enough anymore to make it worth adding another one. We can get by easily three or four days on one charge when we go into the 'battery mode' lifestyle off the grid.
