Dometic or Coleman Roof Air Conditioners

hello
here in tyler we have an rv dealer that sell the coleman mark 111
for 499.00 but you only get the top unit. the face will cost an extra
100.00 and no heat strip. so watch out for this type of ad. i did put
two of the 13.5 units on my prevost. they do a good job but a little
noisy. thanks j.t.

Speaking of high and low speeds.  I spoke with a Coleman tech today and they don't recommend the low fan setting on a hot day.  He said that should not even be an option.  He said this after I told him mine keeps freezing up on a very hot California day (around 100 degrees).  He said to keep it on high and it won't freeze up.  My Penguin freezes up as well.

An update, I bought two high profile 15K BTU Coleman's today because Camping World doesn't stock the Penguins in the 15K units.  They have to be ordered and you have to pay a $99 shipping fee each, and it takes 5 to 7 days to get em.  I want to install mine tomorrow.   

I also listened to both the Penguin and Coleman's in their customer units, and the Penguin had a bit of a whine like mine.  It started up better, mine has to work to start up and I have a 50A power cord.   When I complained about them not stocking Penguins, they gave me a 10% discount off the Coleman's so they ended up cheaper than the Penguins and I took them home with me.

As far as the Heat Strips, I too think they are worthless.  I have one and it blows the air around the cabin and the breeze makes it feel cooler than it is, so you have to make it hotter in the coach to have the same affect, thereby using more power.  Reminds me of the B.S. about reversing your ceiling fan in the winter to push the heat down from the ceiling.  I too, use cube heaters and 2 of them keep my coach really cozy and are really quiet.  However, when it dipped below freezing in NH one winter, I had to run both furnaces.
