Just comparing battery to battery the 6 volt are better because of the thicker/bigger plates .

You will lose a lot of amp-hours of capacity unless the three 12v's are a huge size. Your 6 GC2 6v's produce about 690 amp-hours of 12v power, whereas a typical 12v battery has anywhere from 85 AH-115 AH each, which would give you a max of about 345 amp-hours. You can get huge 12v's, e.g. the 8D size, but you may as well stick with the 6v's.

So the question is, do you need that much batetry capacity. If you seldom boondock and always plug to shore power, there is no need to have a lot of battery capacity onboard and you may as well save weight and money with a smaller battery bank (whether 12v or 6v).

I was just thinking about it all, since the dealer thought I might have to replace the batteries, found out that batteries are fine just had to get a new remote for the inverter/ charger everything is hooked back up and seams to be working fine

First, going from 6v to 12v will reduce the life of the batteries as 12v batteries do not deal with the discharge/charge cycle as well, although they are better at bursts of output (this is why starter batteries are 12v not 6v).

Second, it is about amp/hours, and going from 6 batteries to 3 will reduce the available amp hours by half.

What is significant is how long can your array of batteries maintain a minimum of 12v under load. Doing what you suggest will reduce that significantly, and leave you replacing them more often.

Just for the record, that has nothing to do with 6v vs 12v - it is a matter of battery design. If you buy a quality deep cycle 12v, e.g. a Trojan or Lifeline, they will last every bit as long as a GC2 (golf cart) 6v. And if you found a 6v starting battery (they are still a few made for vintage cars and such), you would find they don't last very long either.

However it is true that the 12v batteries sold by most battery or RV dealers is often designed as a starting battery, or at best a combination start and deep cycle (often called a "marine battery"), and not the best choice for a long life in RV use.
