This is beautiful. What a great idea Howard. Thank you.With kids I am always
either hauling around various inflatables or sucking wind filling stuff up.
I can see mounting the compressor maybe in the back left corner of my 84
engine compartment. A small tank might fit in the same area or perhaps in
that expanse of room around the transmission? Wire it to run off the aux
battery so that just in case you need more air you can get it without having
to start the van? Just exploring this idea some.
For now I have my hands full continuing my self taught AC repair school. It
isn't pretty and should be a separate post.
