I am picking up some of that mattress vent mesh soon for the upcoming camping season, as well as some other goodies. I have a buddy who is looking at making tent heaters similar to the old Zodi but with a few changes and some enhancements, so I am looking forward to testing one if it ever makes it past the drawing board (fingers crossed). If that never gets done, an electric 12v blanket might be in the cards soon!!
Also want to install a USB charging port in the tent for the Cell Phone/Tablet. So much work to do to the trailer...so little time now.
