I live in a doublewide trailor, The duct working in the trailor is no good and I want to replace it with flex. I have a brand new already hookedup 3 ton goodman unit that is supplying the original trailor duct work via 2 8" flex pipes coming from a 16". I need advise, I am not new to hard work but I don't know a lot about duct work and so on and I would love help in the best way, along with parts list help. Here is a drawing of what I am going to do. I am going to cut new floor vents along the outside walls and make it easier to install and maintain the duct work. Any help? Thanks ahead of time.

This is a very complicated request, you need a pretty large trunkline to send the supply to from package unit, then you will need collars and flex duct to run to each boot where the vent is in each room
Let me ask,, I see in several places something about duct board,, maybe you could explain better,I don`t see where you will be needing ductboard
How many supply vents are you planning to make runs to?

I have 9 floor vents total. I really don't know what I need or what's the best way to do this. I again learn fast just I don't want to have to crawl around under the floor of my mobile home every year to fix the lines. Any help would be great!

There is flex duct that is HUD approved for mobile home use. It has a thicker outer jacket and I suggest you use it in your project. I also suggest you do a manual D for your duct system. Anything else is just guess work.
