I have recently purchased a 1994 Newmar Dutch Star 34 ft Class A motorhome. I have been unable to determine where the air filters for the A/C units might be. Both units appear to be connected to the same duct network. there are circular vents in the ceiling. every other one appears to be an intake. there is no service plates in the ceiling and I was unable to see anything on the roof. Any Ideas?

I think they are behind the intake.

They will be serviceable from inside the coach. Look for the air return directly under the roof A/C units.
Tell us the brand and we can give further instructions (or look in your A/C manual).

I have a 2004 DSDP. On mine you remove the inside portion (open spoked piece) of the intake vents. The inside pieces are held in place at the very center, so put your fingers in close to the center and pull. They should pop out. Pull close to the center on them, to avoid breaking them. They are hard to find if you have to replace them. I have had mine out many times without any problem. There is an approximate 5" diameter washable filter in each one. I clean them in the sink, let them dry and reinstall them.

yep....they are inside the intake grilles measuring about 14x7.5 inches...made out of foam and easily cleaned with soap and water...then wring it out and re-install.
The grilles are usually opened by squeezing a couple of tabs which then hinges down exposing the filter.
This is the basic setup for mine which has two roof air units.
You don't have basement air of some type do you?

They are inside (seen from the outside of vents) of the return air vents on my Mountain Aire diesel pusher, up in the ceiling. I have washed them many times and reuse them over and over. Perhaps the previous owner tossed them?

Newmar motorhomes are not like yours. They use multiple output and intake vents throughout the motorhome. I think I have approximately 12 to 14 total vents in the ceiling. They do not have just one intake grill per air conditioner. Their system is suppose to distribute air more evenly throughout the MH and be quieter while doing it. I don't know if it is any better then other methods.

Tom I know most Mhs now have the system you are talking about but on a 1994 model? I didn't know they were using it back then.

If my filters are clean, what would cause my AC to blow so weak in the rear compared to the front?
(I know the front is larger for a reason but the rear "high" fan setting sure isn't anything to write home about)

The Passenger side air ducts are the filtered side ducts. If your rear AC in NOT blowing the correct volume of air, On a Newmar, there is supposed to be an extra gasket installed when the AC is installed to direct all the cold air into the ductwork. From the age of your un it, I will bet that AC has been replaced and whoever installed it did not install the extra gasket. This failure to install the extra gasket (ALL NEWAMARS use this extra gasket) is quite common for installers that do not know how Newmar installes the AC units. Without that extra gasket, the air does NOT flow into the ductwork correctly. Doug
