> I thought the Carver P1 was the ticket here....

Maybe... many things come down to a choice... few things stand out as the
only best choice...

The Carver is more expensive, takes up more storage space under the rear
seat, and uses more power ... and the fan is probably noisier...
But it may put out more heat... dunno...

The Plat Cat is less expensive... the guy did mention he didn't want to
spend a lot... quieter, uses less power,,,, but will likely take up more
floor space... unless you mount it as a portable, which you can and then
take it out for summer camping...
