Refurbishing a trailmanor

Hi! We are hoping to be owners of a trailmanor soon! We are looking at at 1997 2518 and I am wondering if anyone has some tips on refurbishing a trailmanor. We would like to replace the upholstery. Do the cushions remove for easy recovering? Any suggestions on type of fabric to use? What about the mattress covers? I'm thinking we would use a mattress topper and maybe just a queen size spread tucked in when not in use, but would like to hear what others have done. We would like to cover the floor with Konecto wood look vinyl flooring. Used this in our recent basement remodel with great success. They come in planks and strips are glued together, but not glued to the floor itself. Has anyone painted the interior walls? Is there anything special about which type of paint to use?

I realize this may be a project, but that seems to be our weakness. We are still working on our third home remodel!

Thanks for any advice for a newbie at rving!
