I understand the hobby side of life, I certainly have many. If your hobby is the satisfaction of modifying your TT then by all means enjoy it.
Most of my trailer mods were a little more mundane in nature. We unstuffed the fold down sofa so both halves are the same level when folded down. We removed two thirds of the dinette seat so the DW could have a real chair at the kitchen table. The remaining third covers the water pump and is still wide enough for a grand kid. Add to that various hooks, mirrors and such; problems that were solved as they arrived.
I will admit we took a long hard look at the floor plan, so I would not have to do to many changes.
