Are these the right Costco 6v batteries?
I just wanted to make sure these are the 6v Costco batteries people have been buying for their travel trailers. Most reviews I read about them have been positive.

Yes these are the ones - Look to see if they have the slightly larger AH rating for just a few $$ more. These appear to be only the 208AH rating models. The nicer ones will be 220-225AH rating and more like the TROJAN T105 batteries. Two of these 208AH COSTCO 6VDC batteries in series will give you 208AH capacity at 12VDC. Two groups of the 6VDC batteries in parallel will give you 416AH battery capacity at 12VDC.
I too would rather have the TROJAN T105's but they cost in the neighborhood of $150 each so you can see the savings here.
Also I have had good luck just bringing in any dead battery I can find to use for the CORE fee. Most of the time they don't even look at the CORE batteries.
I will be replacing my battery bank with new batteries soon. My original 2008 GP24 standard issue Interstate 85AH batteries are really pushing their life span now. I really want to get the Trojan T1275 150AH 12VDC batteries but they run around $200 each. Will most likely end up with two groups of two 6VDC GC2 batteries giving me around 450AHs total capacity from the two banks. Four each of the Trojan T1275s would give me around 600AH of capacity but there is a large difference in cost here between $360 for the COSTCO batteries compared to $800 for the Trojans. Is the extra 150AH capacity worth the extra $450... Probably not...
I think if you really watch your COSTCO battery performance and take care of when to re-charge the batteries the COSTCOs should last a long time for you. They may not be as rugged as the well proven Trojans...
