We started with a small-ish Tenergy unit that doubles as a HEPA air purifier.

It does a great job removing food smells and air pollution, so we continue to travel with it. Unfortunately, the dehumidifier was too slow for a wet climate, so we also purchased the GE model. It's effective, but heavy and bulky as you said, so I'll be curious if you find something more suitable.
