Answer Wiki:
Your configuration looks fine. One thing you should consider, is adding a password key, so that only these three devices participate in the HSRP process. It just saves problems later if someone else configures HSRP on other devices in this VLAN. Another thing you may want to look at is tracking which will change the priority based on some criteria, and is used to then change which device is the active router for HSRP. You can track interfaces, so if the backhaul interface fails, then it lowers the priority, or track routes in the table, if this is important. It depends on your network, and why you need this level of redundancy.
