Did you really mean "low trail" or low rake? The two run counter to each other.
this is true the heavier front load favors low trail achieved with more fork offset.
I have stuff in my Front Panniers on my Bike Friday All the time,
it has a pretty small trail ..
(the difference between the line through the steerer tube axis,
and the perpendicular line thru the front hub center, as laid out on the ground-plane.)
Older MTB Build,
I've been running SA Drum brake hubs for 25 years,
they now are part of my black ice, studded tire shod bike.
because on Ice, the last thing I want is brakes so instantly strong, I break traction.
they modulate smoothly to bring me, reliably, to a stop.
[it has more trail, for straight line stability, I just have a big Brit saddle bag on it..]
FWIW, rest of the set-up.
I have Mustache bars and old Campag road , pre-aero levers, and pretty Beefy cables .
