Is this possible?
I'm not a truck camper...don't know much about them. If this has been posted before, I apologize. It's a slow day and I'm bored. So.....is this possible?

Interesting thread. Being retired from the heavy truck industry and dealing with multi-axle Michigan trucks, the one thing I see with most of them is the fact that with a NON-STEERABLE TAG you will get a lot of tire scrub (and resistance) from a stationary 3rd axle even if it's suspended with air bags, unless the air is relieved when you turn.
How a Multi-axle unit is set up. Actually, they have a manual 'dump valve' that has to be activated to dump the air when turning. That or a dump and lift valve where underslung bags lift the axle off the ground (after the upper bags are deflated) to mitigate tire scrub and resistance when turning.
With the 3rd axle bags applying down pressure or no bags at all and a conventional spring or torflex setup on the 3rd axle, turning in a tight radius (not driving down the road and negotiating a curve) would become an exercise in extreme tire wear, even possible rolling the tires off the rims, breaking the beads, from side force.
Interesting concept but it needs a way to relieve down pressure on the axle.
I'll keep reading along. I like looking at pictures of old campers anyway.
