2023 Gemini 23TE Wheels

[darkNEskies]

This RV is built on a 2022 Ford Transit 350HD AWD Cutaway Chassis. It's a dually with aluminum alloy wheels. The driver side door label indicates each of the 6 wheels are 16x6 with 205/75R16 tires. All 6 tires are the same Hankook model. I would like to mount a spare tire on a Curt 31006 tire mount. Not being familiar with dual rear wheel vehicles, here are my questions... Are the rear outer/inner wheels the same, just facing each other back-to-back? Are either or both rear wheels the same as the fronts? If front and back wheels are the same, they are installed on the hubs in reverse orientation. If possible, I would prefer to carry an inexpensive steel wheel with a matching Hankook tire as a spare. Thanks in advance for anyone who can help with this.

Same wheels in all 6 positions.

The 4 outer ones are aluminum, and the rear inner wheels are steel. I'm thinking, as you suggested, that getting a steel wheel and proper tire assembly would serve as a spare for any of the 6 positions.
