I want to remove all carpet and put flooring. Makes it easier to keep clean. Tile in the restroom which will take some ingenuity. Granite countertops for all counters. New window treatments the rv ones drive me crazy. Either paint or replace the cabinetry along with repainting the walls. Put LED lighting throughout with some color changing ones for fun. Seal all the plumbing etc. holes for a more insulated area. Install some added stabilizers. That's all I can think of now.
This would be the color theme throughout with black granite.
