Do you have any idea how to decorate a camper
Lots of ideas. Let’s narrow this down-
Walls, flooring, counters, appliances...
Some modifications will void the manufactures warrenty, consult with a dealer in your area.
Priority 1. Easy to clean surfaces.
Priority 2. Make everything double duty.
Priority 3. Batten down the hatches.
I suggest touring the the most expensive campers, trailers, 5th wheels, tiny houses, and mobile homes. Take a notepad and take notes and lots of photos. You can find many sources to buy things, but you can do most projects yourself. You can find many items used in camper repair shops. Mainly, you need to feel comfortable in your home, whether temporary or permanent. And have fun with it. Jewell
