Winnebago Destination 37FL Rust

It's really hard to say for sure without seeing pictures of how bad the rust is. You may be getting upset over surface rust which is no big deal and easy to fix. Some pictures would help immensely.

I have yet to see a 5th wheel frame that doesn't have some rust after a year or so. It's not going to hurt anything. Wouldn't matter to me. Spray on some paint and go camping...

Our 2013 HitchHiker has a powder coated fram and no visible rust. Tell Winnebago to fix it properly.

The frame rust on the Jayco that I posted a link to above had a favourable outcome as Jayco is covering it under warranty.

Some pics sure would be good.

I have the same problem with my 2015 DRV. I think it depends on when it was delivered. If it was pulled through salted winter roads the receiving dealer is supposed to flush the undercarriage with a neutralizing spray and I doubt it gets done most of the time.

Same problem on my 2015 Forest River Grey Wolf Limited. The entire frame has rust blisters. The dealership has been giving me the run around for 7 months.

I certainly believe you are entitle to feel that your coach should have arrived with no rust. However, I don't think that its a concern over the life of the coach. I certainly don't think that its worth the agony you are putting yourself through.
Our 2014 Lifestyle was ordered and delivered to the dealer in FL in March of 2014. It was built during the awful winter of 2014. So it had to be pulled through the salty road slush to get out of Indiana to FL.
It arrived filthy underneath. The dealer cleaned it up and it has not worsened to this day.
I was at the Tampa RV Super Show last year and saw many, many RV's that obviously had been pulled through the Indiana road slush that had a lot of "rust" on the under carriages. Axles are delivered to the manufactures and set outside getting rust on them and pitting for months until a rig is built.
I think a lot of this is just the nature of the RV industry and does not mean a quality issue.
I sincerely encourage you to move along on this issue and focus on enjoying the rig and the years ahead with it. My biggest concern is Winnebago standing behind their product and any other issues that might arise that are far more important (in my opinion) like leaks, structural integrity, etc. Good luck and safe travels.

My coach is a Big Country. Plenty of rust along the bottom of the frame. I could paint it if I felt it was a problem..It will never rust enough to create a problem. I had my springs replaced a couple years ago. I put several coats of Rustolem on the new springs, yup they're starting to rust. It's the nature of the beast. Sorry I think you're beating a dead horse...
