... there will be nowhere to dry stuff indoors much at first...

Yes.....

If the initial heating is poor, keep in mind how a dryer though puts out quite a bit if heat. Not only thru the metal housing giving off heat but, if you filter it and can welcome the moisture in the air, thru the outflow hose.

The back of a fridge does too. A fan set to direct it your way works-- we do that in Fall camping in our tent-camper with the heat-pump end of the electric cooler.
