Between 3 and 4 hundred pounds, carefully loaded under the watchful eye of the client.

She said "Maybe you should make two trips."

Me "I've rather make one."

She offers to take my Rubbermaid bin.

"Are you going to be at the drop?"

"Yes."

"Ok. I was going to bungee it to the top, but you can take it. Thanks!"

The loading dock of this hotel is in the basement of the building, at the bottom of a very steep ramp. I calculate it at about 13% grade. A short hill but one of the steepest in DC. She leaves with my bin, I finish loading the trailer. and head towards the exit. I get about 1/3 of the way up the ramp and come to a stop. I jump off and manage to stop the load rolling backwards, but pushing over 400 lbs gross vehicle weight up the ramp is not happening.

I remember arguing in another thread a long time ago that I can ride a big load up a hill easier than I can push it. I lost that argument, nobody agreed with me, but I still think I'm right.

I can't prove it with this load though because I could neither ride nor push it up this ramp. I managed to get turned around, rode down the ramp and left some of the boxes at the bottom and tried again. Again I could not ride up or push up the ramp. I ended up shuttling the boxes to the top of the ramp in three trips.
