Thank you all for the help. I like the thought of the outboard motor covers. I may go that route if the Honda covers don't work. Here is a the only pic I could find.

The frame is 1.25 x .25 angle. Below each gen is some 3/4 raised expanded steel. There is an opening between for straps and locks. I fishplated the bumper with ~3' strips of 2" x 3/16" where the mounts attach for extra strength, and then used 1x1x.120 square to hold it to the bumper. So that part isn't coming off easily.
The cable is very tight to the gen so using cable cutters they could only get the tip on the cable. I hope it at least discourages theft. It seems to have worked for us so far, knock on wood. Most of our camping is at ORV parks in large groups, and sometimes it seems like I am the only person in the whole park with any kind of lock at all. There are usually gens sitting all around us out in the open.
Each gen uses a short cord to plug into a box just under the rear of the camper. From there 10/3 runs to the shore cord storage cabinet so I can plug in and run going down the road. It is handy for the roof air, etc.
