My thoughts as a current yam pannier owner and ex Jesse pannier owner is
fit a decent locking latching system
Don't tie the locks to ignition key
Offer different size options ala zega pro
Try to get as close in as possible ala Jesse, yam oem
On a std s10 that could mean custom shape lhs but "normal"
Shape rhs.
Don't make them like hb xplorers !
Make frames from stainless steel or alloy ( my old Jesse mounts rusted when the powder coat
Chipped
Makes sure keys and locks are gloved hand friendly
Looks may be important for wider sales intodays trendy adv rider market
