Hello needing some info on My Summer Project. I just picked up a 30k Suburban Furnace for my sled trailer with a 40 lb undermount P-tank. I am planning on doing the walls with Reflectix bubble pack insulation ??? anyone use this to insulate their EC trailer ??? I am also thinking about doing spray on instulation under the floor 1 ½'' thick is this good or bad ??? I also have been doing alot of rearch on setting up my trailer it has a few mods and accessiores in it now. My trailer is a 27ft Royal Cargo (Alberta made) deck over sled trailer. Need lots of info to start any info in my books is good info. Let me know things you have tried, things that work or just things you wish you would have done different. Spell check not working....lol
