A group of us did it last year. A well built 66 on 35's, a Gen 2 Raptor, a box stock 2017'ish F150, a well built Rubicon, and a stock rental Jeep.The road is not all that tough... I don't think the Bronco or the built Jeep ever put their T-case's in 4WD. The Stock F150 might of had to take a 2nd...
