5er wall separation

I've never seen that, but have heard of it in various makes and types. I would suggest, based on the year, to go back to your dealer. If it's newer and on warranty it would be covered. Sometimes you can go to the manufacturer and they will cover it for you even if it's out of warranty. Heartland is very good at working with you. There is a Heartland Owners forum you can get on and search for this issue too. Here's the link.

On uploading pics, there are tips in the technical forum section of this.

It is very easy to post pictures on our forums. One of our moderators, 1492, developed this app to post your pictures. It works for other internet sites also. There is no need to have a separate hosting site for your pictures in order to use it.

It is very simple to use.
1. Upload your picture from your computer to the app.
2. Copy the resulting URL.
3. Paste that URL into your post without ANY changes. No additions or deletions.

Your picture will then appear in your post and be properly sized for use on our forums.:)
