alanzuck,
Hello Dalia and Alan.... we have the same model and we carry our Honda 2000i in the front compartment. We've carried it there for over a year. When I first put it in I was worried about it supporting it but no problems so far. I would like to operate it in the compartment but I DON'T. I think one could operate it in there if you left the door open and weren't in the trailer. If you're sitting outside the trailer watching the miles roll by on the flatcar it would probably be ok.
I always take mine to the rear of the unit to run it. A couple of times I've set it under the front overhang but like it better at the back.
I have tried charging my batteries by running the truck while it is hooked up. It does not really work for me. I think only a trickle charge is supplied... not really sufficient for full charging. An hour or two with the Honda, however, is more than enough!
Good luck and have fun on your trip to Copper Canyon.
