Sleeping in Tulsa,OK

Great advice, I hadn’t really considered the van option just because of the cost of the van. I know I could make the conversion super cheap, but i will have to buy a van. I am good with wood working, but not so good with vehicle stuff- Getting stuck out on the country roads of Oklahoma would not be a good thing… (especially since I am in this rigorous program that doesn’t allow for time off). So I would be looking at a van that is cheap but reliable, and yet space to be convertible. Plus I would need a vehicle that could hold some resale value, as I have little kids at home and I am not quite ready yet to do this long term. At least not until I am out of school and can afford something bigger. All that being said… any advice on make/model?
My needs:
1)Reliable
2)cheap
3)re-sellable
