Understandable. The wife and I just found a house up in East Texas, so we'll be moving soon. I doubt we'll be in any position to buy a camper any time soon, anyway. Good luck w/ the sale. Cheers!
That's probably not a good idea as from about 2006/2007 US diesel trucks were converted to accept low sulphur fuel. I have heard of people doing it, but likely not advisable.
