I went through several scenerios on where to mount my generator including the front bumper (on an extended bumper guard/grille guard). Finally decided on the left rear door of my 2003 Ford van. I am currently having a box built using heavy gauge aluminum. Plan to mount using bolts and fender washers on the inside of the door.. Also plan to use a load binder to add support to the door. It would be attachd to the box and hook into the rear edge of the roof. Should be installed next week. Also, asjssl had a posting with pics on this same subject a few weeks ago. Hope this helps.
