We don't have a ladder either, I mounted ours on the engine cover. Turns out the FMCA plate is tall enough to span between two of the horizontal fiberglass bars of the cover. And the inside of the cover has some extruded grill work (like heavy chicken wire). So I got two long machine bolts, six washers, 4 regular nuts, and two wingnuts. And some foam weather-strip like tape for padding.
Put the foam tape vertically along the back of the plate so when it's up against the engine cover it's got some padding where it's touching.
Put the long bolts through the FMCA plate, the washers and a regular nut on the inside. Now the bolt can't slip through the plate. Put the plate up against the engine cover so the bolts go through the extruded metal plate. When you see how far it goes, you can put a nut and washer on what will be the outside of the extruded plate. Then put it back in place, and put another washer and the wingnut on the inside. I used a wingnut to make it easy to remove or reposition. It could be a regular nut.
The purpose of the extra nuts is to make the long bolt into a proper spacer, so you don't have to torque down the whole contraption against the outside of the engine cover. In fact, there's only enough pressure on the outside to keep it snug. The real holding power (and the torque) is on the two nuts (and washers) on each side of the extruded metal plate.
The only tricky part was finding long enough bolts that aren't too big to get through the holes in the FMCA plate. I ended up with 3.5" or 4". If I needed longer, I would have had to drill out the plate holes a bit.
