RV Repair: Camper Cabinets, queen size bed, lumber yard

Question
I have a camper that sleeps 6 and has the dining table %26 full kitchen. I want to remove the kitchen cabinets %26 table and make the complete area a full or queen size bed whichever fits in the area. Is this something that is possible without damaging walls? And could someone tell me the best way to do this and what would be the best supplies to use for such a project. I would like to think that it wouldn't cost more than a couple hundred dollars and take about a week to do. My hubby will do any builds that need to be done and if it doesn't require certain supplies then he would know what to use. But is it possible is my biggest question?    Thanks for all the help  Vickie

Answer
Yes this is possible you will have to find all of the screws that are there and sometimes they screw the cabinets in from the outside. So that will make it a little unpleasent but as far as supplys you will have to find a pannel that you like from you local lumber yard. I would build the frame out of 2 by 2 pine and cover the top with 3/8 plywood and screw one piece down and hinge the other. fir stoage. You will not find exact match for walls or cabinet but you can get close remember to built it light and sturdy try not to add more weight than you take out.Should take about 10 to 14 hours of time if you are handy. If you would like rv pannels I can get you a number but they are expensive so try lumber yard first.
