Once you get to adding weight to her she's gonna crawl and climb like a mountain goat! 🐐 Those tires give so much space for brass weights inside that even I haven't attempted that yet! 😅 Brass links and axle tubes does add some but I think it's gonna need to be a front heavy 🐷 to pull ... Keep as much of the electronics in the front of the cab down low and under the hood. 😍🤩 I can't wait to see what you do to the rear half!!! 🤜💥🤛
