There are guys that post on you tube about building lifep04 batteries, its not that hard and the BMS will protect you at all times. I use Daly BMS with bluetooth, I can see the state of my batteries anytime I'm in the house, the same would work for your coach. If you really want to be safe and have the last for years only charge them to 90% and discharge them to 25%. This will insure your safety and they will last for over 5000 cycles. Check out this guy and look for his battery builds.
