Q. We’ve been looking for a new trailer and have a question regarding the
relative merits of aluminum siding versus fiberglass. It appears, from the salesmen we’ve
talked to, that aluminum has the advantages of overall trailer weight, the ability to
repair easily and cost. Gelcoat fiberglass presents a seamless appearance and claims of
increased durability as compared with aluminum. We don’t want to have to purchase a new
larger truck at the moment, so weight of the trailer is a factor, as is cost. Can you
discuss the pros and cons of each material to help with our decision, please? – R/J. M.,

A. First of all, you should remember that any salesman you’re talking to
is going to promote the positive aspects of his company’s product, no matter what it is, at
the expense of the competition’s product. That said, both side wall materials are popular
and durable and can offer long-term cost-effective benefits for the RV buyer.

Corrugated-style aluminum is often used on lower-cost RVs because it’s inexpensive, and
repairing it is normally a simple process of replacing panels rather than repairing the
existing panels. Smooth aluminum of the type used on higher-priced RVs can be costlier to
repair because the shop is dealing with larger pieces of material. Smooth fiberglass can
often be repaired in the same fashion as an auto-body panel, using filler and a fiberglass
patch kit, so replacement of large body sections isn’t always necessary. The costs
associated vary greatly depending on the size and location of the damage.

As for durability, each material has its good points and will deliver good service. A
bicycle handle that accidentally bangs lightly against the side of an RV may bounce off
fiberglass, leaving it unscathed, whereas corrugated aluminum may be somewhat dented. A
puncture in a fiberglass side wall or molded end cap, after a heavier impact, may call for
a major hole repair, while the aluminum panel, similarly damaged, may need to be completely
replaced at a widely-varying cost. There’re good points to each siding material.

The weight question is a toss up. Fiberglass that’s manufactured with a lauan plywood
backer can be pretty heavy, and doesn’t necessarily provide much, if any, weight advantage.
Better to look at size and options when you’re looking at the lower-weight aspect of your
prospective trailer. — J.J.
