Sweet build! Just throwing this out there for you, but I insulated my hot side equipment (all Sanke keg holes) with Reflectix insulation sealed with duct tape then shot with insulating truck bed liner. Very efficient and sturdy, plus it looks good. Check out my HLT build in my threads. I would post a link but I'm on my phone. I will be following this thread and can't wait to see the final product.
