Older Rhinos fit in a pickup, what others models do?

[GoldToyBox]

First post and I don't know much about UTVs.
Looking for a used UTV but I want to transport it in the back of my full sized pickup. I know Yamaha Rhinos fit (I've it done a few times). I was at the Tulare Farm Show and notice none of the new models (any brand) will fit in the bed of my truck. Per salemen: no more narrow tracks, too many roll overs.
What other models/manufactures/model year will fit in the back of a pickup.

thanks for any and all advice, thoughts, ideas, etc.

Hope I put this in the right place?
