Whats under the ice cream truck in dusty divot?

I've been curious as to what was under the ice cream truck for ages and thus I set out on a quest to find out (I basically spent 15 mins in front of an ice cream truck trying to dismantle it.) and here's the result.

It's just a chest........... I am very disappointed like everyone else who tried to do it.

and not a single legendary came out either
