Buying a deep cycle battery
So I've been looking at deep cycle batteries and needless to say there are a lot of options. I drive a '78 Chevy Itasca 21' and I imagine my usage load all be relatively light, as there aren't too man...

Actually there are very few choices in the world of DEEP CYCLE batteris
GC-2,, You have the choice of 215/220/230 and 250 amp hours depending on manufacturer and sub size.. Not all (epically the 250 size, will fit your RV.
Of these Trojan is the best but also the most expensive (Flooded wet)
the GC-12 (12 volt) is now starting to come down in price.. I think that is around 150 Amp Hours.
Now you can also get AGM, these do not require a lot of maintnance (They are a sub class of Maintenance Free) but they are very costly and there is disagreement as to how long they last... LIFELINE is best here but again, more expnsive.
Maintenance Free (Wet cell not agm) are VERY VERY VERY hard to find a true Deep Cycle... MARINE/deep cycle yes,, DEEP CYCLE no (M/dc is not nearly as good for RV use).
Finally we have OPTIMA,, A sub class of AGM with 60% of the capacity of other batteries of the same size class (for obvious reasons).
My Recommndation GC-2's. Buy them in pairs (6V+6V=12V) put each pair in series (Bat-ery) and treat them just as you would a single 12 volt Size 4D.
