Wow. The camper did NOT want to come apart.
We ended up hammering and pulling and tearing to get it free.
I guess screws, building “cement” caulk and regular caulk, plus a few layers of paint really hold the pieces together.

Thanks to Sam though we got the front and back off.
Next week it’s take off the top and decide whether to leave a shortened version of the side panels on or take them off completely.

It’s much easier to clean out the detritus and debris with it open.
There’s nothing of value left in there so if someone cleans it out for me it’s no loss for me.

In fact, I think tomorrow I’ll drive down to the dumpster and just start tossing trash.
