Dash Vents and A/C

[Kota]

My 95 Classic seems to be a bit of a customization (or bastardization) of a 360 coach designed for a P30 retrofitted to a Spartan EC2000.

Unless I'm missing something, there is no outside air source for the dash vents. The air inlet is a register that takes cabin air near the passengers feet. It has a huge blocked off grill area that was origionally intended for the 454 radiator. I'm thinking of designing an air intake plenum with a cabin air filter to provide fresh air to the dash vents. I'm planning on replacing the dash vents with 2" aircraft style eyeball vents. With a couple low on the center consol for the Dakota (the dog). The dash A/C is also a big weak. Thinking about upgrading the compressor, condenser, and evaporator with something newer and more effective. Maybe an aluminum finned tube from the rear to front for more condensor capacity.

Any thoughts, suggestions, or comments?

Since we don't see these coaches much, possible for you to post some photos of your current set-up?
Thanks, Derek

Minor comment: Most coaches leak so much air going down the road that any extra "fresh air" is really unnecessary. It also would put even more load on the system, cooling and dehumidifying the outside air to interior temps.

Probably the most effective thing you can do to increase the capacity is a second evaporator. They can be fairly easily plumbed into the original high and low lines and can be located where they would do some good, like in the rear of the coach. Usually there is enough compressor capacity, and even condenser capacity, but the evaporator capacity is marginal, due to dash air flow restrictions and/or evaporator coil size.

That said, I do not know your coach AC system at all. These are general comments mostly based on the old GMC motorhome I owned once, and the 310 and 26' Argosy MH I had.

I would think, if you look close, that you indeed do have a fresh air vent.
On my Clipper, it is located facing the ground.
If you just want fresh air, you could install a two way vent in the sidewall.
These are on ebay, come in steel, plastic or aluminum, and some have interior finish panels in various colours. They are easy to install and can be reversed for wet weather travel.



Do a search for what you might need.

I installed one on the Clipper to flood the batteries with fresh air as a lot of heat is trapped in this area on those hot mountain pulls.

I take some pictures next week. I'm off to work for a few days.

Check out a company called "Vintage Air". They specialize in retro fitting A/C to old Hot Rods.

My 1987 Suburban has the front and rear AC option.
It always worked very well, even out here on the 100+ deg days.
I see no reason why a good compressor should not be able to handle a dual system.
