We've been camping for the past 4 weekends and except for the first weekend, temperatures have been below normal. Mother Nature isn't showing any of warming up either. I've been looking at areas where comfort can be improved.
Today's project was insulating the inside of the propane compartment wall that protrudes into the basement storage area. On the 30.5MLOK the walls in the basement storage area appear to be decently insulated, except behind the area with the battery disconnect switch. In that area the steel wall from the propane compartment cuts into the basement and is not insulated at all. It appears to be air tight but appears to be 1/8" steel that gets very cold and draws heat out of the storage compartment.
For this project I used 1" un-faced foam board and 3M foil tape. I simply cut three pieces; two sides and a top. The tallest (right-hand) panel was cut 1/8" long so it could be press-fit into place. The other sides were taped together, then the sealed to the walls using spray foam.
The area where the propane compartment intrudes upon the basement storage is behind this panel.
This is what it looked like with 2 of three sides in place.
And the finished project.
The entire project took 30 minutes from start to finish.
Our upstairs has suffered from poor airflow ever since we bought the rig in 2018. I finally decided to do something about it today. The riser ducts that go from the underbelly to the upstairs duct was a mess. There were two flexible runs that were about 18 inches too long and sagging badly. However what I think what was killing the airflow them most was the poor alignment of the ducts to the holes that were cut. I estimate they were blocked by at lest 33% or more.
The only photo I took of the project. This is after removing the flex duct to see the alignment of the mounting plate relative to the hole that was cut.
To get this project going, I had to remove the interior wall. This also required removing the P trap for the shower to get the wall to come out. Once everything was out I removed the flex ducts, shortened them, then reattached with the holes properly aligned. Everything was sealed with foil tape to ensure no air leaks.
I didn't do a good job taking photos as it was getting late (and cold), so I don't have any more for this project.
The total time was about 2 hours start to finish. Removing and re-attaching the interior wall took most of the time.
