I don't think you'll get any noticeable heat from running a computer all day in there. At the weekends I tend to have the desktop on all day and now the xbox as well and its still cold and damp in here! About 16c and over 70% humidity by the evening, which is only 2c better than the morning. I have 3 exterior walls and a concrete floor though which is bad enough to try and heat, I just can't see you being able to heat a caravan adequately in winter. Only good thing will be the airflow though it should keep the mould away at least.
