I own a 2008 Little Guy Silver Shadow (built by the previous company). This particular model had the battery next to the hitch and has NO galley. The rear hatch is locked with the standard, t-handle locks that Little Guy uses. These locks swing down and lock behind a "handle" mounted on the trailer floor. There are three locks.
On the way home last weekend I decided to put some extra weight at the extreme rear of the trailer (to lighten the load on the hitch) on the floor, in the empty space left by the foot end of the mattress. I put my Honda EU2000i generator .. a large duffle bag with camping gear .. and a few other things. I (as usual) locked all three t-handle locks on the hatch and locked both doors shut.
During the trip home I heard something rattling as we drove down the highway. It only lasted for a few seconds. I did not pull over to check. When we got home I checked the trailer and did not see anything obvious that was missing or loose. It was hot. I was tired. So I didn't empty the trailer for a few days. When I finally did I noticed that the rear hatch was open and only held down by gravity. All three t-handle locks were still locked, but they had all slipped out from the handle mounted on the floor. Thus (I imagine) the hatch was bouncing in the breeze as I drove down the highway. I haven't checked everything (not sure what I packed in the car vs in the td) but it seems like I lost an old collapsable Coleman stove stand (I think I just dropped it on top of the big duffle bag) .. and that was what I heard clattering/rattling down the highway. Luckily the generator did not fall out (I would have been SERIOUSLY pissed)
Aparently there was too much weight in the extreeme rear of the TD and somehow it caused the hatch to bounce up and unlatch while still locked.
Now I realize that this will not matter much to most of you as most of you have a galley in that area, but I thought I'd mention it for the rest of you.
