air condition vs humidity

I installed an 8000 BTU window AC in a Chevy 1500 express ... The AC cooled the van just fine but the humidity was way high (over 80 percent).

I got a used 7K btu LG portable to deal with temps over 90 when my roof top on my van wasnt keeping up (in direct sun). It stands in the van with the exhaust hose out one of the little sliding windows. I tried to use it as often as possible in conjunction with my overhead AC (when I had adequate amperage). The water streams out of the overhead to the outside, but the LG inside is not plumbed to get rid of water so I run it without the dehumidifying function. That, and a small clamp on fan directed right at me seemed to keep me and my dogs cool enough. I did notice that just when I stopped after driving the van would really start heating up and I eventually figured I needed to open the hood to let the engine cool off. I also put up material between the drivers compartment and the rest of the van to limit the heat from the engine and the front windows. Now all I have to do is figure out how to keep my van heated since the overhead doesnt keep up with that either when temps drop below 40. I did get some insulation and will try that.
