Ladders are designed to carry the weight of fully grown adults. I'm 200# and the ladder on my trailer could care less.
If you are hanging the tote on the ladder just run a rathhet strap around it and ladder to keep the tote from swinging or banging the ladder.
I have a Rhino 28 gallon tote and after several thousand miles no issues at all.
