Sam's club batteries are perfectly fine, I suspect Costco is the same way and for most folks that are budget conscience and don't have money to burn a real bargain. These are the best bang for your buck in capacity and cost and Sam's does have a 3 yr pro rated warranty.
If money is no object and you have deep, deep pockets you can easily spend two to three times more for other brands but only get a couple of Ahrs more capacity and perhaps a couple yrs longer "warranty".
No matter what brand of battery you go with, they ALL can be damaged or have their life severely shortened if you do not "care" for them properly..
Make sure you have a multistage converter/charger.. One that will drop to 13.2V for "storage" mode when you are not using the RV or battery.. This is extremely important to reduce the water "usage", anything over 13.2 will boil your batteries long term and will require very frequent water level check and adding.
Check water at least yearly provided your converter can go into storage mode and that voltage does not exceed 13.2V.
For converters with 13.5-13.8v output, you will need to check monthly maybe weekly or risk boiling the water out and exposing the plates to air (bad)..
