All good points Dan (as usual). I would love to communicate with someone who has had one for 50 thousand miles or so to understand better how well they stand up.Wow, I am shocked to see that photo. The closest Jeep has an AEV rear bumper, AEV tire carrier, larger spare (35s? 37s?) AND the AEV fuel caddy.
From experience I know that is a significant amount of weight.
All that weight is hanging off the now extended rear, which puts it further behind the rear axle than ever before.. AND that whole rear extension is just "bolt on" - there is no welding.
Keeping the tires stock would certainly help with the weight problem.
