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.

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.

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

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.

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

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

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:

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.

I just found carrier ac's at www.rvexit.co Ebay listing

. New in the box $ 526.00 to $571.00 Heat strip. Shipping $99.00 My Colemans both of them shot cra- . Even after I spent $$$.00 to have services on both. But then again it is a 1982 AS 34 foot Limited / Coleman 6746 A Mach lll EL Series. I hope one ( 1 ) will do as the $$$.$$ are tight.

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.

**azflycaster** · 06-14-2009, 04:31 PM

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!
