Case in point. We just had our very own Jack14R show Mr. Liberty and the gang how to get the autostart voltages right on Libertys watchdog system.

He should get some type of an award for that.

Do we have it covered or what.

Tim whilst everyone spouts and pontificates about their otr and ability to ship butchered meat cross country with out spoiling we have a lurker out there.

I am unaware of any liberty out there that comes close to his total cooling BTU

The bus is a 98 Vantare H with OTR a/c + large central a/c basement unit for the house AND 2 criusairs one in the front room and one in back.

I just got off the phone with Alek he has a pair of these things in his H Royal one cools the left side one for the right good design either or both. They are hands down THE quitest a/c units out there and you never catch a breeze like off the cruseair or roof air.

If I were starting from scratch this would be 1 piece. Can you fit those things in the basement of an XL?

Hi Tim. I'm glad you decided to jump into the POG pool. I used to live in San Jose and Mountain View while attending San Jose State back in the early 70's. Man has the area changed since then.
I found a Coach for you. http://www.rvonline.com/single-ad.as...SearchMethod=1

It has an additional sleep area and it's definately a nice Liberty.

Joe,

While I canot disagree with the use of a package heating and cooling unit in the bay as some conversions use, there is a disconnect with what owners are professing.

The single loudest argument against OTR is the presumed loss of bay space. Maybe that is the owner's repeating the blather told them by the salesmen, but it is repeated often.

The reality is that OTR takes up the equivalent of 1/2 bay. It is in the third bay position and the remaining 1/2 of the bay space is actually the fuel tank. So when a packaged system is installed it is usually in pairs. The combination of Cruise Airs and a single package unit is not common. A pair of packaged AC units takes up......A HALF BAY.

As to the capacities, the conversions I have seen with the packaged units use 26,000 BTU size, two being a total of 52,000 BTU, which coincidently is the same as my four cruise airs at 13,000 each, or one package and two cruise airs. They all fall short of the 80,000 BTU+ capacity of OTR.

If space is truly a consideration then a coach with four roof airs addresses that concern.

Jon,

Our H3-45 Royale has OTR + 2x26,000 BTU's AC/Heat units in the basement,

Alek

Alec,

That is what I have typically seen when packages are used. For house AC it appears the norm for a 45 foot coach is 52,000 BTU of cooling. It is either the package, the four Cruise Airs or four roof units.

Some converters only use three units on a 45, and entertainer coaches often have at least 5 roof airs.

Thanks Gary, that is truly a very nice coach. However, I will have to wait another four to five years to afford it!

You Liberty boy's have opened my eyes to another viable option. I appreciate it.

Please keep the comments coming. It is a very entertaining thread, for me at least.

Tim

All the Marathons I looked at had 3 cruisair units are they 13 or 15000btu if they only use 3?

Joe,

This is only my opinion based on an experience we had. Two 13,000 BTU Cruise Airs will not keep bus temperatures below 85 when the OAT is 96 to 98 degrees. When the interior temps were in excess of 85, even though the OAT had dropped to 94, after 3 hours of running all four Cruise airs (total of 52,000 BTU) we had just gotten interior temps down to 78-79.

If the bus interior temps are maintained at a comfortable temp (for us it is around 72) then three might be able to do the job, but as we found out if they are warm to start with four units are barely adequate. There was just too much mass of heated interior to cool down.

I recognize that what is an acceptable and comfortable temperature for some does not work for us. Also, our 40 footer had three and apparently the shorter length only required three, but our 45 in our opinion definitely calls for 4.

Point of information:

Our Marathon H3 has 4 cruise airs (plus OTR), so not all Marathons are limited to 3.
