I admit, I am a bit paranoid about possible fires on board now. I made my first real check of the refrigerator on our 2016 Axis. Took off the outside inspection panel and did not find any big surprises. I did find the bottom partially covered with some type of very small tree buds and mini-pinecone looking buds with some in the burner area. A few minor cobwebs.
Took out the shop-vac and compressed air and got it all completely cleaned up. Just a piece of mind thing and a suggestion to all not to ignore this aspect of maintenance and inspection. Don't forget a look at the water heater as well.
