    Had my APU installed by dealer about 6 years ago, they used the flexible, ribbed tubing to conduct the air flow from the HVAC unit. Seems to me that the ribbing would cause inefficiency and a lower air flow than if I were to install smooth tubing of the same diameter.
    By going to a smooth tube, it should provide more cooling and heat .... right???

    Anyone any idea if my theory is correct??

    Thanks

    Probably, but the benefit reaped would be considerably smaller, than say, improving the efficiency of the APU blower. I'm sure there's quite a bit of room for improvement on a lot when it comes to APUs and their design, but they're a god send either way, with fuel being as costly as it is; and the according screwing over of company drivers not getting to idle.

    Oh, and you might try insulating the blowers duct. I know the blower ducts have a thin layer of insulation already, but blowing 50 degree air into a fiberglass box sitting in full sun during a 100 degree day in the LA sun will rob that truck of its cooling ability when it's going through ducting that only has an inch or so of non-isolating insulation.
    Might try some owens corning and duct tape, make all the colors match so you don't like you just crossed over the Mexican border- lol.
