Wood or Aluminum Frame?

Mine is aluminum frame and tin exterior, so no delam issues. Because of so much aluminum and a full I beam frame, I have a low dry weight and high carrying capacity. And I have no worries about rot hidden in the walls. I sleep like a baby at night.

We went back to stick and tin to avoid delamination. Problem solved.

Research Fiberglass Trailers. They last forever & hold there value. Look at the ones built in the USA and Canada. This was stated on one of my post:
Charlie Young Jack Gilliam Correct - I sold my fiberglass Casita after 5 years to upsize to a fiberglass Escape. The Casita sold for what I paid for it - and it sold in less than 48 hours after l posted the listing.
Look at direct from the factory. They build for you so you have a better quality. Lazy Daze out of CA. build Class C. Taylor Coaches out of Canada build Trailers. https://taylorcoach.com/

I like the idea of aluminum. And still my wood frame is holding up just fine. Corrugated aluminum siding has no issues.

Is the wood or the Aluminum frame sturdier? Thanks!

More fodder.....
This from NUWA about aluminum vs wood construction;....which was posted a letter form on NUWA website for years.

Why doesn't NuWa use an all aluminum structure like popular Indiana manufacturers?

NuWa made the decision to begin the use of aluminum structure based on marketing and the fact that many people were concluding that an "aluminum caged" product was superior in construction technology, weight and strength. Our 40+ years of experience as a leader in 5th wheel design suggests that may be "flawed" information. We have proven that wood construction need be no heavier or less strong than aluminum construction, that is built properly. We now build both materials, and are comfortable doing either, however our opinion is still that wood construction provides a superior product, and today we use both in the construction of our trailers. The strength of the NuWa trailer is actually created by the superior and light weight Blue Dow foam lamination concept.

NuWa uses an aluminum substructure in the sidewalls and ends of the coach only. No aluminum in the floors or attics, where metal promotes conduction of cold and moisture resulting in condensation.

90% of the walls are Blue Dow Structural Foam, rather than wood or aluminum. This creates a superior insulation and the only product with a guaranteed sidewall R Factor. (Water absorption in standard white foam reduces R Factor over time, and the use of Blue Dow Structural Foam eliminates this problem.)

NuWa's aluminum substructure sidewall is actually a "hybrid" wall, as we core fill the aluminum with wood in those areas where additional strength is required, because aluminum will not hold a screw. Not so with the lower priced brands. With NuWa's combined use of wood and aluminum substructure, you get a superior product because of NuWa's unique Blue Dow foam vacu-bond process, which makes the sidewalls virtually resistant to water penetration.

Water leaks are the nemesis of all RV's and water doesn't destroy aluminum like wood - nuff said?

Sadly, almost all RV have plywood floor. Any leak WILL rot the floor over time.

Agree ! The problem with "eggshells" is that they are expensive and not very "stylish" either outside or inside. Also, they tend to be on the small side, couples or families with only a couple of small children.
