Thanks for the reply Salty. Yea Ide agree it might be less hassle over what I am using but I do at least get the ambiance of the flame with the Mr. Buddy OF course my unit has 2 furnaces on it.

Two furnaces? Basement models have two?

If I needed to jack my shell up slightly, where would be the best points? Currently working on the floor and I need a little more space.

In my experience, the easiest way to get more clearance is to back the trailer onto 3-4 2x10s. This will give you roughly 4-1/2"- 6" of additional clearance.

The other option is to lift it from the mainframe that supports the leaf springs and axles. Study the mainframe before the front wheels and after the rear wheels. There should room for a lift point as well as blocking to support the trailer.

On our 30P, I started on one side and lifted it 6". I used a combination of wood blocking that gave each support point a 12" square pad. Then I went to the other side and did the same. I ultimately lifted the trailer 12-14" off the ground.

For a additional stability, use floor jacks where the bumper attaches to the frame. At the same time, deploy the electric jack as well.

When you are done, you will have 4 primary lift points in the middle and 3 for stability. By the way, absolutely never use concrete blocks for support! I went to HD and found some 6x6 and 4x6 timbers that had been reduced 70% due to warpage. For every level of blocking, insert a square of ply/osb to spread the load.

Take your time on this. You want to be at peace working under the trailer. In my case, I was able to restore/rebuild the axles, brakes and suspension at the same time.

Thanks Bob, I literally mean the shell, currently replacing the floor and I can tell I will need a little bit more space in an area (maybe 1/2inch) and trying to decide where to lift the shell without damaging anything.
