Reimbursed for traveling to manufacturer?

I'd take it back to Winnebago and sit on their doorstep. Bug the heck out of them. They'll get you right in. When they say the slide water issue is fixed make them show you by a heavy stream of water from all directions aimed at it. I don't know about reimbursing you for your travel. You could try. The main thing is get it fixed and forget Camping World in the future.

After it's fixed make a nice siteseeing trip out of it and test it out before getting too far away.

Best of luck!!
