Mark Rogers, I really appreciate what you did for me. Unfortunately my brother-in-law also took his tape measure to a 3500 he found, and it's probably not going to work (wheelchair most likely too wide for the space if we remove the passenger seat). We are disappointed but have a couple more contacts to check before ruling out the NV altogether. Thanks a lot, guy.
radin2son, thanks, I have spoken to Chris in the past, a very knowledgeable guy. He said the wheelchair conversion companies are no longer working with the NV.
