I have a EB with voyager top on a SMB west conversion that had 33"s and now 35" Nitto Trail Grapplers.
Not only to I wheel it pretty hard but I let newbie disabled guys drive it with handcontrols through my non-profit Disabled Explorers
Go to Youtube and search Disabled Explorers and there are some moab videos.
The way SMB did the built the CG felt nice and low, 46gal fuel tank, 16gal water tank, aux batteries and all that was mounted at floor level.
Also the Alumiess Roof rack was very light even with Rigid LED lights, solar and basic cabinets.
Did lots of off camber stuff, and while it feels crazy since you sit pretty happy, it is very stable.
I also ran with the sway bar disconnected full time and even with hard hiway speed swerves there was no issue.
