Check out the profile "uneek1" This is my brother mikes envoy (envoy and trailblazer have the same suspension) there are alot of pics on how it was done. There is more than enough room for re7 bags. The front is cake the rear is the problem. Expect to cut the floor out from the rear seats back for clearance. Door jambs and doors will have to be cut with runing 22s with 255-30-22. Anything bigger and you will have to relocated rear door latches. Keep that in mind. Let me know if you have any other ?s.
