My little fifth wheel remodel

I love the sofa! It looks like a futon--is that what it is?

I would add a taller & wider light blocking pair of panels over that bedroom window, for heat & light control. Would keep it a lot cooler.

If I get an older RV, the plan is to paint the walls a light gray, woodwork a warm white, go with a medium neutral or green for fabric, and add color with accent items that can be easily changed out.
