Hello,
you are welcome. We've tested it on Debian and Raspbian only. The problem should be in service identification, which may differs at RedHat. 

vrrp_script chkhaproxy {
    script "/usr/bin/killall -0 haproxy"
    script "/usr/sbin/service haproxy start"
    interval 9
    timeout 3
    weight 20
    rise 2
    fall 4
}
