You were very impressed with the ceramic paper. Do you still recommend
this for heat insulation and noise reduction??

Where did you locate the evaporator cabinet?

>blowing hot air out thru the floor . ...

This is more along the lines of what I am thinking of doing. Where did you=
=20
get the blowers? Did you fabricate your own enclosures for the evaporator &=
=20
condenser? Where did you purchase the tubing and fittings etc for the freon=
=20
lines? Did you have any problems with the blower kicking up road dirt and=20
plugging up the condenser coils?

I know this is going to cost more than just replacing the rooftop A/C but I=
=20
really like the idea of cleaning up the roof lines and getting the weight=20
of the A/C off of the roof and down lower.

I am also thinking that it would be nice to find a compressor that mounts=20
horizontally or is low profile enough to fit between the frame rails under=
=20
the floor. I just don't know where to look for parts & pieces to cooling=20
systems. Are you aware of anyone selling this stuff on-line?

I do like the idea of disassembling an existing air conditioner for the=20
major parts. At least that way I know it is all matched properly. And used=
=20
air conditioners are reasonably cheap and easy to find. I just wish I could=
=20
find one with a compressor that is low profile enough to fit under the=
floor.

Not at all. There are a number of us who have been thinking about ways to=20
get rid of our rooftop A/C units. Its very interesting to hear how you=20
actually did it.

Can anybody come up with some pictures on this modification?
Would the condenser portion fit in the propane compartment if one goes to=
the smaller propane tank? Any thoughts?
