6V AGM Batteries

Thanks all for the responses. I know that Trojan and Lifeline are very good batteries and will last a long time if cared for. I was just trying to find an AGM in 6V that was a little more affordable than the Trojans and Lifelines. I'm wanting to move my house battery bank out of the stock metal can designed for the batteries due to size and the only location I have is under on the the bench seats of the kitchen table which is in the living space. If I use any flooded cell battery I have to figure out how to vent them. I can really only go down under the coach which suggest a powered vent. Really didn't want to do that. So, trying to figure how I might be able to afford AGM's. They don't require a vent. I was really looking to find if any of you have used or heard of this VMAS Charge Tank batteries and if they are any good. They say the plates are made to mil spec. I suppose that good but really don't know.

Thanks for your help.
