Toy Hauler Option

Hey everyone! Love this forum and I’m always reading and learning something new here from all the full timers. I’m still a ‘wannabe’ but have an executable timeline and a fairly clear idea of what’s needed (for us) to undertake the full-timing adventure. We’ve had time to consider several things and are at the point we’ve settled on our method of travel and living once we hit the road. A 5th wheel is our choice and with that we recently became aware of an option that several have used to augment their mobility while parked. Some are using toy haulers to haul a Smart Car in the garage then using it to zip around their destination while the 5th wheel is parked. So yes, the Smart Car is light enough and the loading ramp is rated high enough to do this. Mechanically and structurally it’s well within the capabilities of certain toy haulers, and the garage area doubles as a living space while stopped. My question is; does anyone here on the board use this set up? What are your impressions or lessons learned? Or if you’re not using this set up but know someone or have run into someone in your travels using this set up what we’re your impressions?

Thanks!
