There is a needle nose KW in small scale, like the honest John missile kit or the Begins moving kit. It's around 1/50 or something like that. But yes, I agree, we need a 1/25 version to go with the 351.
To answer your question... most custom trucks don't have spread drive axles. The spread drive axles is mainly for heavy weight and oversize. The 10' 1" is for trailers. The most common spread on drives is 6' 6", I believe. There are some custom heavy haulers that have the spread axles, but not many.
I also love, I mean love, goin for drives on mountain fire roads and power line access roads. I'm not into the heavy off road, rock crawling stuff, but there's something about the cool, clean air, and sound of nature when I stop to watch and listen. The little vehicles I work on give me great mental time. It keeps me on my toes. My styrene hobby is almost like golf, without all the walkin. I love to golf, despite not going in about 5 or 6 years. There's something frustrating, aggrivating, yet relaxing being on the course. I need to dig out the ol clubs and give a go again and go slice it up.
I really like the blue truck. I'd like to see a few more of it. I like the fuel tank changes, the exhaust reconfiguration,the step switch and that paint scheme is probably my favorite on the Freightshakers. I also like the changes on the red one too. The updated door latches to make it appear a few years newer than the kit.
