I could go into details explaining but it might be better to look at this site and what they are selling. Look through and you might get a reasonable understanding of what I'm speaking about. This is NOT the size unit I would use for a motorhome.
What the site has is a good explanation.:
HE150 Air-to-Air Heat Exchanger - Smarthome
Now if you go to this site you will find a smaller unit made by Panasonic. This is one you can adapt to a motorhome. Look for model number PE FV04VE1
on the page. Since if fits between standard framing it's not too bulky.
Panasonic air to air:
In my opinion Mitsubishi is the leader and have been making air to air heat exchangers for a long time and I'm familiar with them. They are bulky units. Mitsubishi components are used in products produced by Renewaire.
You might want to look at the model EV-70. Not as small as the Panasonic unit.
The Renewaire site:
RenewAire Energy Recovery Ventilation
The EV-70 is small by house standards but still oversize for a motorhome since it moves too many CFM. A 40 foot motorhome only needs 14-15 CFM. EV-70 manual: http://www.renewaire.com/_assets/fil...0Man_MAR08.pdf
The Panasonic can be set up for 10-20 CFM and I think the most adaptable.
Non of these use much power. Far less than a dehumidfier.
