Aluminum vs. Fiberglass Siding
Aside from the obvious aesthetics and cost difference, is there a glaring advantage or disadvantage to one or the other?

Disadvantages (Fiberglass); If not built correctly or you have a bad enough leak, the adhesive or materials can fail resulting in delamination. Also if you damage it it's not easy to fix. The factories tend to replace the entire wall panel when damaged. Costs more to build and purchase.
Most water leaks occur on the roof OR at the roof to wall joint or around the windows. IMHO, RV manufactures have done little to solve these problems.
One piece, aluminum skinned roof, with preformed exact sized flashing around vents and A/C openings, would go a long way to solve a major part of the problem. That, in combination with a better edge transition system (like Rain Kap( and better sealants (EternaBond Tape ?) would be a major step up in build quality.
As for windows, take a page out the boaters book. Butyl tape.
Less those changes would add several hundred $$$ to an average TT, but would reduce maintenance and extend the life by many years.
