Several of the motor homes we've looked at had what looked like white, 4" round vents on the front face at the bottom of the couch. What are they for? They can't really be vents can they?
Yes... My AquaHot system has one in the base of the sleeper sofa. All the other vents (output) are in clear areas of the walls or cabinet bases, but, in order to keep us (the sofa users) nice and cozy, they put one in the front of the sofa that blows out on our feet while we watch the television. Super nice in the winter!
