Hi , and a belated happy birthday .
Have you considered something like this ?
I always try to buy real quality when choosing this kind of gear, and in fact my 'Outback' bag (without wheels) is still up to the job after 20 years and several trips around Asia ! Strapped to the back of a Carabao on one or two occasions.

I might need the wheels now though.
