Toppers are great for improving the heat loss upstairs. We have a Pucer cover and love it in winter, having used below zero Celsius. Nevertheless, there can still be quite a significant heat imbalance between upstairs and downstairs when running the overnight heater. This only matters if you’re using both upstairs and downstairs beds. Similarly, it is not a significant issue, but rather something that benefits from improvement, or some ‘finer tuning’, so why not...
Having taken some inspiration from a similar German made, but expensive contraption, I made the attached. Ducting and two ducting ends bought from Screwfix for just under £10.
I cut one of the ducting ends to sit perfectly into the Cali’s B pillar vent, requiring no modification to the Cali or any additional attachment. It also leaves half of that vent uncovered to continue heating the downstairs.
I will either attach the upstairs end of the ducting with the help of the Velcro strap on the upper mattress (as pictured), or get a removable suction cup (such as this) and tie to hold it at the front of the cab.
Not bad for £10 and 15 minutes effort in my humble view. Hope helpful.
