I can't seem to find a solid answer for this, so I thought I'd seek
the collective wisdom of the group.

To wit:

A trailer rated for 4600 lbs GWR means that it will handle up to 4600
lbs of weight - including the trailer.

Now in my world, it seems to me that a "safe" load would be, say 80%
of the max rating including the trailer. But I can't find a
specification or recommendation that states the exact percentage of
what is considered a "safe" load.

I know I'm over complicating this some what, but I'm just trying to
cover all my bases.

I remember that 80% figure from vehicle towing capacity.
If the specs say my Ranger can tow 3500 lbs...2800 would be a safe load
with a margin of safety.

My old Easy Hauler trailer was rated at 1400 lbs... but my boat alone
weighs at least 1300 lbs.
My new trailer is rated at 2000 lbs...but the axle is rated at 2400.
