1975 Bigger 19ft (turning into Ice Fishing Palace)

[Icefish]

Hello community! I have been looking to build a much larger ice fishing shack using an RV. My current shack is 10ft by 5ft. The Bigger will give me 19ft x 7.5ft and be a fiberglass capsule.

Here is the Bigger I got. Ive gutted it and will get to building it back out.

Hope to get a bunch of good advice.
