I have the basic Tahoe model T-Bag , like this "Expandable Tahoe" except mine does not expand (I guess mine discontinued?). So mine is always just about 7.5 inches deep.

When I put it on the luggage rack, it extends over the end of the rack about 1-1.5 inches, and that sags down a bit, and I think it hides the tail light just a tiny bit, more so for those sitting higher up in an SUV or truck. Other riders behind me have said it seems OK.

I know I can put the T-Bag on the pillion seat, but the short sissy bar makes it not attach too securely, so I'm working on that. What I am interested in is a way to firm up / extend the luggage rack to prevent the sagging.

Any suggestions? Thanks.
