I have Cardinal , you can go-to thier website and see that the trailer is framed throughout. Mine is painted also lf you take care of it it will stay nice for a long time Mine is a 13 and people still ask if it is new. Cardinal also does an excellent paint job .

It is an owner lack of maintenance problem, not a type of construction issue. There are plenty of 20-30 year old units around. Even if Adzel is used in the walls, almost everyone uses plywood in the roof and floors, so again regular maintenance is needing to protect your investment.

And, delamination is like your face pealing off...not good. The outer surface separates from the base material from water intrusion.

You might want to review this thread within the New Horizons owners forum.

http://www.irv2.com/forums/f269/nh-n...ls-360823.html

It will provide some additional context on wall construction and the use of azdel. Post #9 is from the CEO of New Horizons.

High gloss exterior is purely aesthetic, and you can really see the difference in person when looking down the side of a rig, especially a clean one.

With brands that skimp on the gelcoat you can easily see the individual fiberglass strands through the color on the exterior walls. Does that make it weaker? Not necessarily.

Up to you if appearance is important.

Our trailer is the vacuum laminated walls. Still looks brand new but we do wash and wax it twice a year. And inspect the roof seals often. No issues so far!

Regardless of construction, any boat or trailer that is maintained on a regular basis will benefit in the long run.
ORV uses vacuum laminated walls with 2" rigid insulation on all their rigs. I just wish the decal designs were painted on instead of vinyl stickies. These are hard to keep from looking crappy in 5 years. I put 303 on them, but the sun will win in the long run.

Based on the thread I just read, it looks like the only thing that is guaranteed to delaminate it the Adzel.

Stick and Tin won't delaminate. Which btw is what I probably would go with if I get a small TT for quick work trips. With aluminum (or vinyl) sided wall, I'm capable of handling repairs worse case. I really do like my FW walls (vacuum bonded), but anything major goes wrong, and its a huge financial hit.

Others will delaminate because the plywood absorbes water, swells and separates. Azdel doesn't absorb water and if the proper adhesive is used, it should not separate from the fiberglass outer skin or the aluminum studs. The aluminum studs are also impervious to adhesive, so anyone using hung wall construction has to use the right adhesives for the materials used.

There are potential risks with all types of construction and many of us never have a serious problem. I haven't across 6 different units and 30 yrs.

I think we just buy a few dozen sword and daggers, paint the different processes on the blades and you guys can pick your favorite "process weapon". We'll have an all-out brawl and the last man standing can claim his process as superior. Otherwise, there are no guarantees to any of them. It's all about the cost and maintenamce.

All 3 (hung, laminated, roller) are excellent construction methods.

Which one stand the test of time is depend on many factors.

The underlying structure is in alignment.

Amount of flex in the trailer frame.

How the rigid foam is fit into the wall.

Time and pressure in the vacuum chamber.

Number of times through the roller

The number of clamping bars use for hung wall and for how long.

Cleanliness of the assembly area

Proper type and amount of "glue" is used.

The surface of the aluminum is prepared properly.

There is no pieces of insulation on the aluminum before the wall panel goes on.

The wall panel is laid on not dragged over the aluminum frame.

Is management pushing the line past capacity that day/week/month?

Fyi, my Cardinal has welded aluminum studs in the wall, which is fitted with insulation and then the hi-gloss gel coat exterior and interior wall is Vacuum bonded to the framing. They have pictures of driving a car onto a wall being used like a ramp. Much more to the wall than just insulation for strength.
