A very well done thread HERE from the tech issues forum--a little off track as it relates mainly to design characteristics of true deep cycle batteries.

I have 2 Power Sonic PS12750 batteries in my TC. http://www.power-sonic.com/site/doc/prod/102.pdf I have seen them go for $150 before, pretty good for a 75 amp/hr AGM.
I would liked to have gotten bigger ones but there were free from work because a BIG UPS blew up - can't complain.
OK I bit the bullet and bought 2 Everstart 125AH deep Cycle Type 29 Batteries. Now I just have to trickle charge them to top them off and I'll be good to go for next weekend.
Thanks for the info gang.
