We had a chance to test out the changes I made to the camper and I can say they definitely helped. As I said earlier, I swapped in a digital thermostat, added a layer of Reflectix insulation under the mattress, and used a Sportsman blanket with the shiny side down over the roof of the bunk.
On Friday night, the temps dropped just below freezing. We set the thermostat on 60 and stayed comfortable all night. The digital thermostat was much better at regulating the temperature and we did not notice the drastic swings in temps that we did last weekend. There was also noticeable less cold air coming in from under the mattress...plus we had pillows this time.
On Saturday, I made some Reflectix cutouts to put in the windows of the bunk. The outside temps did not get as low as Friday night, but we kept the thermostat at 60. I can definitely say we noticed a difference with the cutouts in the windows. There were a couple times when I thought I was going to have to get up to kick down the thermostat.
$40 for a big roll, I'd say this Reflectix stuff is worth it and the $20 digital thermostat was also worth it.
No more outings planned until May.
