Alex, stay in the most forgiving arrangement you possibly can until you are done schooling, education, and seeing what the next four years bring.
To that end, stay in a month by month apartment, or rent by the month, but do not even consider tying yourself to any kind of a camper. You need to think about the pitfalls that happen with camper life, the people that are successful are happily retired, know each other well, and have experience.
Living in close quarters with a partner, two dogs and a cat, is pretty stressful for a month, not many of us can even imagine four years. Life will change, stay with a flexible future.
