Just a thought from bitter experience. Never mind the price (which is good, by the way), feel the weight! I have 2x120ah batteries and they are DAMMNED heavy. Vaguely thinking of getting 3x80ah ones instead. Same power, but I might at least be able to move them into and out of the vehicle!
Cheers, Tony

I paid $235 for a hundred AH over a year ago. Sounds ok to me.
I'm thinking about 100AH with Cold Cranking amps for a starter battery at the moment, $265 on Ebay.

This could be a good strategy if the battery is mounted in the engine bay of the vehicle as these batteries will often recharge more quickly from the engine's alternator than a deep cycle only battery.
Before the days of AGM batteries a former tag-along operator that I did a number of trips with found that his best option for an auxiliary battery was the Yuasa Overlander 4WD (starting) battery.

At the risk of starting a controversy I'd be "iffy" about parallel connecting three batteries. There are downsides to parallel connected batteries and these are compounded as more batteries are added to the bank. One of these is that the life of the whole battery bank is only as good as the life of the first one to fail. When parallel connecting batteries steps must be taken to ensure the load is spread evenly between all batteries.
I would also suggest that before purchasing the batteries you discuss this with your battery supplier to check any special requirements and any warranty issues. This also applies if operating two batteries in parallel.
