You should do both. Better battery and inverter closer to the posts.
I would do the solar as it works on recharging even when you are not around so long as the sun shines. I would NOT consider a Zamp panel. They are quite over priced for what you get.

It's about 15' of cable from battery to inverter. I lean towards getting a deep cycle battery instead of moving the inverter.
One question: if I get a deep cycle battery, is the alternator upgrade or solar panel more important? (I can probably fit a 160 watt zamp panel on top, but don't have room for much bigger).
More, probably later today.
Thanks John, Mex, and All!
