I carry a short piece of ply wood, probably 3x3, when it rains I push the Honda under the truck or trailer and use the plywood on the windward side as a precaution. Most of the time at the Coast, because of fog and mist I will just set it in the back of the pick up with topper and let it run in there.
Mine cost me close to a grand so I will take top care of it.
If it was considered a disposable generator i might care allot less because it wouldn't hurt that much to replace it!
