My 2023 BRGB will be a Kenworth T600A (after much digging thru my stash and deliberating) on truck for my four axle trailer project. I will be adding the third tag axle from KFS, possible fenders for the rear axles from Keystone, frame stretch to accommodate third axle. Undecided if I will use fairings (have a couple different styles) or redo the front fenders (add lower extensions) and have exposed battery boxes and fuel tanks. Picture for inspiration
