Hi Mark,
Welcome to the forums! I believe that your unit already has a support frame installed for AC installation. No clue on the furnace. Some of our 60's gurus will be chiming in shortly. I am more of a 70's kind of guy

Thanks, hopefully the support frame is there. Can i stand on top of the trailer?

With some caveats: stay off the ends, try to stay on or close to the rivet lines indicating ribs, wear soft sole no slip shoes (I wear top siders) and if you are a heavy weight I wouldn't. FWIW I go about 215 and have been on top of my trailers many a time. For me the best method of access is to lean an 8' step ladder against the rolled up awning.

Ok, I was wondering, i go about 215 also. Where is the best place to get parts?

Your Overlander should have electric running to the location where the AC should be installed. I think the factory can tell you where to cut the hole and find the power line. You need to have spacers between the skins so that the new unit can clamp to the skin. I doubt that you have them in your trailer now. I replaced the AC on my 75 and had to add the spaces to install the new unit. Be careful on the roof, but it is very doable.

I bought my unit from these guys:
eBay Store - FAMILY RV PARTS STORE: RV AIR CONDITIONERS, CARRIER A C OPTIONS, SATELLITE SYSTEMS
I bought the low profile Carrier 13.5K unit with the heat strip option. It was by far the best price I coulld find.

Thanks Richard, I can see the wires on the inside they come through a hole. I will need a 14" x 14" hole, Right? Is the picture of you replacing your unit? I will check out the ebay store.

14x14 is the standard hole size for the AC. Yes, that is me (with the hat) on the roof getting ready to drop the new unit on. I did the swap at the 4CU restoration rally in Albuquerque earlier this year. Getting the old unit off was a major PITA. Getting the new unit on was a lot easier. I had forums member Zep showing me the way on this, he was a life saver!

Cool, So two ladders and a walk board just for extra support. Any thoughts for the heater replacement?

The original AC became a part of the roof.

It "DID NOT" have any framing built in.

When you install a new Ac, you will have to install a couple of "stringers" and cross members between those two stringers.

If not, the new AC will cave in the roof, when you hit the first bump.

Were you able to get a drain pan on that unit,I`m wanting to put one on my GT ,but I don`t want the water running down the side.Dave

Thanks Andy, I think i have seen photos of the installation somewhere. Do you have any suggestions for the heater, water heater,water pump etc.

Carrier AC's, do not need a drain pan.

It would be a very rare day, that it would spill water out of itself.

Suburban furnace, Atwood water heater, either 6 or 10 gallon, and either gas or electronic ignition, Jabsco water pumps.

There are cheaper versions of the above.

I suggested top brands that offer top perfomance over many years.

The new designed Carriers have a drain system that is built into the unit. I attached my existing drain line to the connector that was provided. You can install it without the drain line, but you may have some water running down the trailer side on humid days. From the site where I bought my unit:

THIS IS THE ALL NEW DESIGN THAT YOU HAVE BEEN WAITING FOR..HOT OFF THE ASSEMBLY LINE.. ALL CONDENSATION CAN BE DRAINED AWAY VIA HOSE.."NO BLACK STREAKS".

Thanks Andy, Do you know what model number for the suburban will fit in? Does any water heater fit?

[mark m]

Richard, I have heard about the carrier, I think i will go with that.

Mark.

Suburban NT-s0 SP is a popular model.

But, you may have to be a little creative to install it in a 43 year old trailer. Attaching it to the duct work, is the hardest part.

You will need an adapter plate for the water heater, even if you us a 10 gallon version, since the outer dimensions are much smaller than what you have now. It's not a big deal to install the plate with sealer and Olympic rivets, and then cut a hole for the new water heater.

I am on vacation, so I cannot give you any dimensions until I return on the 22nd.

Mark,

If you are going to toss your old AC unit let me know. I'm looking for parts for my 67 Overlander Armstrong TAC-110 unit.
