I have worked with John on planning a conversion for my E-Series van, and he has spent a significant amount of time answering questions, and guiding me through the process. I flew down to San Diego to drive their shop van, and my brother and I were treated very well. John took 2-3 hours out of his super busy day to walk us through his shop, answer questions on the Ford vans, as well as the Sprinter RIP kits. These guys obviously have a great reputation for a reason, and I highly recommend them. They do top notch work, and are one of the best shops in the country for Mercedes and Ford suspension works and 4×4 E-Series conversion.
