Hi All, I'm Ed and I am getting close to buying a van to build a DIY camper van conversion. My choices are either Nissan NV3500, Mercedes Sprinter, or Ford Transit. I plan on doing a full camper conversion that includes wet bath, galley, and sleeping for 2. I have done a preliminary layout and the NV is a little limited due to length, but I think I have fit everything in, I want to choose the Nissan due to several factors including cost, warranty, ease of maintenance. However, I have a question about warranty work. Can it be done at any dealer, or just Commercial dealers?
