It's gonna be heavy! They start out at 4500lbs (base, stripper model) when just sitting on stock 10 bolt axles. When you upgrade to 1 tons (Dana 60 front 14bff rear), beefy bumpers, a winch, rock sliders, a cage, etc, the weight adds up quick!!! I'd be willing to bet that a K5 built beefy enough to handle 40's is gonna be pushing 7000lbs when loaded for trail riding. Mine is built for 40+" tires (350,sm465,203/205doubler,dana60,14bff....but sitting on 37's (and soon won't be mine hopefully! (selling))) and I'd bet it weighs in at around 6000lbs now without a cage, bumpers, a winch, or any gear in it.
I don't run MTR-Ks since they weren't out yet when I built it. But, I see no reason why they wouldn't be up to the task. If you check out Petersen's fourwheel and offroad's Ultimate Adventure, that's all the tires they ran this past year, on heavy Chevy's like Cousin Willard and that sweet regular cab one, and on their big Ford rig too!
Sent ya a PM!!!
