I have set QoS up over many tunnel wan connections. My problem: Most of my tunnels are point-to-point wireless bridges that vary in bandwidth depending on the quality and distance of the shot. To apply QoS to these interfaces at different bandwidths, I have to create multiple policy-maps on some devices. I have two 3845s, one allows shape average percent on tunnels, the other does not. One running 15.0(1)M2and the other is 15.0(1)M3 IOS. I have not been able to find why certain devices do not allow bandwidth percentages. I also can apply it to most of my 3825s, but not all.

You likely answered you're own question, i.e. a feature unique to a later IOS version. (I wasn't even aware this could be done, but then I have worked with any 15.x IOSs.)
Might be a good idea to add tunnel path-mtu-discovery to your tunnel interfaces and you shouldn't need qos pre-classify (unless your doing QoS on the physical interface too and you need to examine pre-tunnel IP header info).
