Aluminum or wood frame?

Aluminum vs. wood makes for an interesting discussion but pales in comparison to proper floor plan.

If the floor plan is right. If the cost is right. If the TT weight is not an excess burden to the tow vehicle; then the choice of wood vs. aluminum might come into consideration.

Wood rots, aluminum corrodes, both of which are signs of water leaks which may ruin everything around them, regardless of what they are made of.

The manufacturer chooses wood or aluminum base on the manufacturing methods needed to meet their target design and market price.

what is the comparable timing between wood rotting out of control and aluminum disintegrating beyond repair?

I bought a new 27-foot aluminum-framed Jayco featherweight in 2006 because I liked the smooth fiberglass construction and the light weight of the aluminum framed chassis.

This trailer has been great. The light weight makes a big difference when towing in the mountains, and the fiberglass looks as good as when it was on the dealer's lot.

I was going to buy a new Airstream, but the $17K the Jayco cost me was about what the depreciation loss would have been on the Airstream after five years or so. Besides, the Airstream was much heavier, which turned me off too.

Lance uses aluminum framing with the aluminum coated with Alodine which helps to prevent corrosion:

Lance also uses Azdel in the walls, which means a lot of things:

And on the fiberglass, they use Lamimux 4000

Lance's are light but built as strong as possible!
