Can I hack into my heat ducts in new TT? Extra AC / heat.

I love this thing to death, but the horse shows we've been at (two in the past month since we've owned it) have been brutal heat / humidity. 95 w/ 105 heat index - Central VA, Kentucky, etc.

The TT is a 30' Springdale Summerland 2570RL with a good size slideout, but only has a 13.5k AC unit. I guess this is right about the limit before they install a 15k unit? Towards late afternoon it gets up to about 78 inside which bums me out since I thought the thing would be ice cold.

Anyways, we have a 12k BTU portable air conditioner - I just don't really want it inside the trailer. One thing I dislike about them is that the condenser air supply is at the unit, yet the condenser exhaust is vented out the hose. This creates a vacuum that most people don't think of. Generally it means that same amount of exhausted air is being sucked in from somewhere (which is HOT air!) But that's not really my concern, I just want to keep things clean and open.

I have all these lovely floor furnace vents that are connected together somewhere.. is it possible to run a supply duct tee off the furnace that I can just attach to the face of the portable unit? I can just sit it under a table or near the RV, etc. Same for the heat. If I get a semi-powerful forced air or ceramic heater, can I hook it up to the vents so that (if I ever actually go winter camping)I know the pipes are safe? It has the "arctic package" which I guess just means it has an enclosed floor.

It only has a single pass-thru storage on the front of the unit and I have ZERO clue where and of the ducting or components / tanks for the unit are located otherwise.
  • Some other improvements might help, sunblock window shades, reflective vent "pillows", etc that may help the unit you have work better.
  • The problem with using heat ducts for cold air is they will sweat, being uninsulated.
  • Probable best just to install a 15k unit, best in addition to the one you have, if there is another roof vent opening. The Maximum you can expect is at most a 20 degree drop between the intake and the outlet. In the area you are talking about, unless you are in full shade, one 13.5 unit will not handle the load. Either get another unit, get a bigger unit, or another cold beer. These units just don't have the air handling capacity for a 30' rig. Probably OK in the shade, but in full sun, no way. Sorry, but that;s the way it is.. Notice in my sig picture, there are two 13.5 units on top, with 4" at least of roof insulation.
