Yup, need to check all the values. High values in Q count could indicate a
problem like congestion. I have noticed RTO of 5000 on eigrp stub routers when
all is well.

RTO OF 5000 is not a problem. RTO of 5000 with a Q count > 1 is a problem.
In general, i have noticed that EIGRP's RTO defaults to 5000 when adjacency
is formed via a logical interface such as Tunnel interface.
Thanks
