Nov 20, 2017Either type of wall will provide you plenty of years of service. While each have pluses and minuses relative to each other, neither wall type is really ultimately better than the other. Really it just boils down to personal preference.
For fiberglass trailers, delamination isn't something that happens serendipitously. It's usually the result of a problem that has been long ignored; for example, a roof or window leak. The same type of problems will cause rot in the structure of aluminum sided trailers. While delamination can occur, it's not a rampant problem in modern trailers. Along with travel trailer, lots of 5th wheels, Class A's, and Class C's are all fiberglass sided.
If maintained properly then either type of trailer will provide years of problem free service. Being proactive with keeping the trailer weatherproofed will help prevent tons of problems down the road. As with any RV, if you neglect the maintenance then it will eventually fall apart.
