I want to convert a step van. I would really like to RV an old UPS brown van (so much character) but I understand that they are never for sale. Anyway, I want aluminum. I want diesel. And I want highway gearing. Insulation would be nice. So would A/C. <br><br>Anyone know of a good place to learn about this? Or a site where the person RV'd one up? So much to learn, so little time. Advice appreciated.<br>
