Margie:
We have a tiny Pelonis unit which does a great job. It can really crank out some heat for its size.
Pelonis Honeycomb Ceramic Disc Furnace - Model PF-1212 (1500W variable, 5A min draw, 12.5A max continuous draw, 5200 btus, $65 @ Amazon, auto/man, heat/fan/off, adjustable thermostat, overheat protection, safety tip-over switch, 6-3/4h x 5-3/4w x 5-1/4d)
Obviously with heaters you need to watch the amp draw as it relates to what source you have (20, 30 or 50 amp campground power....or generator) and what other devices you are using in the rig.
With many heaters the amperage is determined by the setting on a switch (low, medium, high). On this Pelonis unit the amp draw and heat provided is determined by the variable thermostat and current ambient temperature, meaning it will draw a lot if the rig is cold and you have the thermostat way up, but then as the rig heats up the amp draw goes down.
If you are looking for tiny, they don't get any smaller than this I don't think. Love the ceramic disc feature, for efficiency and safety too.
