If the cabinets are wood all you need to do is make sure they are clean, do a light sanding and prime them. If they are a plastic veneer you will want to make sure the veneer sticker is attached well still. If is the latter, I would use a satin finish spray paint and then seal them with a poly. You can get matte poly if you don't want them shiny

Cabinets are not real wood in a camper. Here is one solution should you decide to take on the task. http://thenewlighterlife.com/how-we-painted-our-cabinets-without-fuss/

PAINT THEM OR COVER WITH CONTACT STICKY BACK PLASTIC.

Repaint the cabinets using chalk paint and polycrylic sealant.....I would do an antique /off white if you want to keep the wall colour. If it were me, I'd recover the benches with a more up to date material and make curtains to match...

Paint them! Dianacirce70 is correct. I would also go look at the color combos and features of newer RV's by visiting your local retailer. I always go poke around on our local lot down at Campingworld, it is right next door to Walmart, so why not??? ☺ This will give you ideas for curtains and how to recover the upholstery.

I love what this woman did to her camper..... https://www.littlethings.com/vintage-pink-trailer/

Paint is your friend. Make sure you clean the cabinets before resurfacing with anything, so it holds up longer. If you or a friend sews, those cushions are pretty easy to recover (and if it's shorter than a shower curtain is long, they make excellent fabric sources).

Last idea- if you want to, add curtains or a bamboo shade for privacy. Have fun, invite your friends over to help!
