Hello, fellow Excel peeps! Just picked up my vintage trailer yesterday in the middle of a rain storm. Good thing, now I can find if there are any leaks! So far, just one minor leak in the mid ceiling and some minor trickle from a cracked window that needs to be replaced or just resealed. Will scour around the unit for any more. So far, everything seems to work. I want to update some functional stuff, such as the gas line hoses and bathroom sink spout/shower head combo. I was wondering what other people have done with adding insulation on these units, as they don't have thick walls.
