Steve thanks for the info. I did not have time to make this call before
my vacation. See below for comment

I mounted mine on its side and the return air gets drawn in through
the hole where the stock heater once was. The problem with this is that
the return air is also drawn across Exhaust pipe which over heats the
 return air and causes premature shutdown. On the trip I solved this
 with a block of wood to keep an opening gap under the seat.
I had hoped to solve this with the remote thermostat. Looks like it's
time to
remote it myself or remount the whole unit.

I used high temp silicone.
