Started bolting down the tie-downs. The factory ones were screwed into those steel plates you described on yours, so they were more secure than I originally thought. The bolts had a sheet-metal screw-like tip on them. I couldn't get a nut to go on that, so I'm just buying new machine bolts to replace them, with washers and nylock nuts. The front center one is the only one I can't get to--it's up under the belly insulation, and I really don't want to pull all that down.
The unit is going back to the dealer today to have my punch list of stuff fixed while we're still under warranty. We'll see how that goes...
