Looking for input on economical 12v deep cycle batteries.

Replacing 2 12v deep cycle batteries for the RV. Almost never set up without 30 or 50 amp service. Would like to keep the cost at less than $180 for the pair. What suggestions/recommendations...

Seldom boondocks, wants thrifty service. A pair of engine starting batteries subjected to HALF the cycle depth will last eight times as long as a pseudo cycle RV battery. A 20% DOD with a pair of CAR group 27's is a lot of energy.

How long is the free exchange with a Costco auto battery?
substantial price difference between an auto group 27 and an RV group 27.
