Hi Matt,
Welcome to our site! Glad you found us.
We're here to help, and it doesn't matter what brand of camper you have; we're happy to assist.
You mentioned you have a 35-foot Sunline Nomad. We all learn from each other, so that we may learn something from you on this one. I do not recall "Sunline" using the Nomad series or style name.
But, Skyline did make a Nomad brand/series camper. Sunline and Skyline were competitors in the industry. I have a good camping friend who had a newer Skyline TT. It was a nice camper. Skyline was also in the manufactured housing industry. I'm not entirely sure, but the trail I found indicates that Skyline sold the RV side of the business in 2014 to EverGreen, which then went under some time after.
So, with all that, did you read a label that was a little worn or faded and mix up Sunline with Skyline? Again, for us, we are OK with folks with other brands. The way campers used to be built and, sadly, how they leak, are not brand-specific, and we may still be able to help, as resting a Sunline or Skyline can involve the same techniques.
If you have a Sunline, please tell us more about it, as we have a wealth of Sunline information, including many copies of the original sales brochures and manuals we can point you to.
The VIN can also be helpful, as Sunline VINs start with 1LC. Skyline, I believe, might begin with a 1HG manufacturer code.
NOTE: VINs for models before 1980 used a different format than the current day 17-digit VIN. Is your camper older than a 1980 model?
Good luck with the camper repair, and again, we're here to help as much as we can.
John
