I checked the archives, but did not see anything that matched. I am interested to know if anyone has had any experience in building a sleeper in a cargo van. I am going to get the longest van I can, but do not know how much to allow for sleeper space. What would be the minimum amount of cargo space to have. I would appreciate any input on this as well as the technical stuff wiring the sleeper for fridge and such as that- Thanks in advance for your help.
