PS, the maker of these
http://www.electrowarmth.com/fleet.php
who is the reseller to
Cozy Winters, is phasing out the 30x60 ones too.
They are only going to have two models, the 42x60 like I am getting, and a 36x60.
If one needs a larger size like the 54x60 or a 60x60, you will have to look elsewhere.
I will have to do some research as to other makes out there too, as there are some that have the built in auto shut off timer so you can go to sleep with it on, and it shuts off after awhile.
So mine might be up for sale later on, maybe even before my first camping trip if I find another one out there better suited to the size of the AirLand mattress.
