Regarding your awning question.  I purchased the A&E last spring and have been very happy with it.  It does not require drilling into the vehicle if you get the attachment brackets.  You will have to drill the awning though to attach the brackets to it.  I have never taken it off since last spring because I am afraid to see if it is bending my rain gutter?  I am not sure what size it is off hand and could check my records for you if you need.
