please remember if you are living in it the tow vehicle needs enough room and payload to handle all your stuff as well as the camper. That camper (and a cheap old tow vehicle) will require constant attention. If cash is that tight id be looking for a cheap apartment since you will be paying for this that and the other thing constantly. Full time for the sake of it not for cost savings.
that said, park it and save for more tow vehicle IMO. if you can get into a 2011+ f150 with the 5L or the 3.5L eco boost you will be miles ahead in reliability, comfort and mileage.
