[hypoxia]

I gave a lot of thought about installing a Jun-Air.  Instead I repaired all of my air leaks, now the compressor only comes on when doors are operated.  I still give the Jun-Air some thought when in a campground since the compressor must annoy the neighbor on that side.  The best improvement I did on the Thomas compressor was installing a muffler on the unloader as described in this thread. Compressor Unloader Muffler  The unloader is completely silent now.
