I agree with pretty much everything that has been said. Just one small correction; the 9.25" doesn't require an external battery, it's internal
rechargeable one will last for a long viewing session. The 9.25 is easy for a reasonably fit person to carry complete, whereas the 11" is approx.
45% heavier, and more awkward to carry, so you'd probably have to remove the OTA. The 11" also has seriously long focal length, meaning
that a number of deep sky objects won't fit into the field of view even with your lowest power eyepiece. Of course this also applies to the 9.25", but to a lesser extent as it's focal length is about 17 or 18% less. Neither of these scopes is suitable for very low power sweeping of the sky. I personally would not plunge into buying an expensive scope. I suggest that you try and attend a star party and try some different scopes, or try to find someone reasonably local who has a similar rig, and spend an evening with him/her.
My choice would be the Skywatcher collapsible 10" Go To Dob; fits in a hatchback, both parts easy to carry, wider field of view.
