I want to see it, Robert. Show us pictures, please. I have one, and figured maybe in the luggage rack?
Don't know about "genius", and I can't take credit for the idea (RobA and Dave and I discussed a couple weeks ago), but it seems like the ONLY possibility!
I measured the area on the side of the cab. You will have 0.3" x 0.46" x 0.122" (7.4mm x 11.8mm x 3.1mm) to fit a decoder. Due to this conversation, I altered the deign the make a little more room. I hope that's enough space. If what Robert says is true, then there should be a decoder that fits. BTW, if anyone is interested in my projects, I post the latest information on my website: www.thezmaker.com
An ESU Nano fits easily in the fuel tank area of the 44 tonner and, IMHO, is easier to get in the USA. Can I assume it will also fit in the 70 tonner?
