Hello, I am new to this site as well as pop-up campers. My in-laws gifted us their 1987 Coleman Sun Valley, my husband used to go camping in it with them but that was a LONG time ago and now we are trying to get her in shape and ready to camp again. So where do we start? What are the priority things we should be looking at to make sure she is good to go? Any helpful hints would be very appreciated. Thanks in advance!
