I have the Solo High clearance. I run 285/70/17 and I would not be able to use the underneath for that size tire with the solo installed.
It does sit a ways away from the vehicle but it doesn’t concern me. I fit a bag with recovery equipment on the back side of the spare and also drilled holes...
Got the bumper and winch on. Looks great and works great.
Have a 3inch front 2inch rear Pro Comp lift.
This dropped my front end significantly.
Will be changing shocks and set up ASAP.
