Delamination Tiffin vs Newmar

I old am in the final stages of buying a 2007-2009 newmar or tiffin 40 ft diesel pusher. Someone at a dealership that sells both told me that if you happen to have a leak on the roof (and down the wall) of a newmar you will not get delamination because of the way their walls are constructed with their type of insulation and they have a "breathable" wall which will dry out. Tiffin on the other hand is thermal bonded (or something like that) like all other rv manufacturers and would delaminate. Is this true? I am very interested in this because on my 1999 Winnebago adventurer I had a skylight crack without me knowing it on a trip and it delaminated all the way down the wall. Thank you for your help.

the misinformation from the 3rd world is incredible. Its like believing a salesman. I have been on the forum for a pretty long time and dont believe I have ever heard of either brand with a delamination issue. Do a search and eliminate goofy info from those who really dont know squat.

Newmar uses a "hung wall" construction. It is NOT laminated so delamination is impossible. We have owned two Dutch Stars, a 2000 and 2002. None of them ever had any delamination or roof leaks.

I do not know about delamination but there is something in the years you talk about dealing with roof rails ( not sure that is the right term) My 2005 has rails that run the length of the roof. If I understand and i might not be using the correct terms. Tiffin in 2006 or 2007 went to a fiberglass piece that wrapped from the roof down to the walls. There was an issue with those and tiffin was replacing all of them for free. Again I might have the wrong terms but should be easy to find out about.

But the "hung wall" will still come apart if leaks go uncorrected. It may not be "delamination", but its still water damage.

Wasn't it in the 2005 or 2006 model years where most RV manufacturers changed to a different wall substrate? The new material was not moisture absorbent and delamination became less of an issue.

In 07 and 09, tiffin had wood in its walls so they could delaminate. Take it from another salesman that sells both and does know what he's talking about. Things are a bit different today. Today tiffin doesn't have wood in its walls anymore. Now when it comes to walls, a hung wall is antiquated old technology. They can say what they want about their 2x3 wood joist floor with blanket insulation, the tiffin has 1 1/2 x3" steel frame floor, block foam insulated and fully laminated floor. A hung wall can still be damaged by water and a laminated wall that the manufacturer says cannot delam due to not having a wood backer can still delaminate on the inside of the coach. That pretty wallboard you see on the inside, has a wood backer. Took one in trade last Saturday that you could poke your fingers through on the inside but the outside showed no signs of delam. Personally I still like newmars look better and would personally buy one over a tiffin but the tiffin is a better way to build a coach.

I would prefer that any #1 post that starts a thread would be Trash-canned immediately if somewhere in the post it says "someone" said this or "I heard that" or "They say....."

There are plenty of threads on iRV2 that make sense and are based on apparent facts or real experiences.

IMO
