24DC is rated deep cycle trolling. This is not really a starting battery even though it has a MCA rating of 690. 24DC will work fine in your RV although it is not a large battery with high capacity compared to a 27DC or 29DC.
OK maybe a little less capacity compared to Crown and may not live as long but it will come at a lower price. Charging, usage and maintenance will have more effect on service than brand IMO.
What do you really expect from this battery?
