(((Update))) we bought it / 1995 Lance squire lite 185

Wow , nice!
That looks a million times better inside too!

Truck looks like it’s riding fine and that camper ain’t too heavy.
If it feels like it’s rolling a little too much in the corners you could wedge the lower overload springs. Like lower Stable loads but you can make some out of plastic felling wedges and square u bolts for about $50.
To try it out, cut some wood wedges and hose clamp them in for a test drive.

Or a sway bar, but you likely don’t need much if anything with a lightweight camper.

Congrats!
