Has anyone ever had their living quarter couch re-covered or replaced?   Wanting something that isn't slick to sit on. 

They can be easily replaced if thats the route you choose. Find someone or company that does RV interiors and its pretty darn easy. I did the job myself a few years ago because the cheap brown leather cracked and looked horrible. I replaced it with a nice , non slick one in less than an hour. 

So you just went and baught a new couch or recovered it?  It is the only thing in the trailer I don't care for because you slide around on it and dang near shoot off of it if you try  to sleep on it !!!!

Remember, a LQ is just an RV.  Any RV place should be able to help you.
