The Roadster HPC to Model S Adapter arrived and I will be picking it up on Monday. I'm going to order another one for myself for road trips and make this one available for permanent placement at the 70A Roadster HPC in Centralia at Burgerville. If you are still interested in kicking in some money for the adapter you can e-mail me via my TMC ID. I'll reply with more details and information as it comes in. P.S. Be sure to pick up a jar of Burgerville's secret sauce while you are there. It is only available seasonally and it is THE best. The same is true for their Walla Walla Sweet Onion Rings.
