Aluminum is typically found on the light and ultra-light weight RVs today and it is used mostly due to the weight savings.
Over all, fiberglass is the preferred unless weight is an issue in today's market.
From your statements, one might conclude that equivalent design travel trailers will be heavier if fiberglass skin vs. aluminum skin.
To prospective buyers, I would say check the weight specs.
For instance, I did a dry weight comparison of my 2014 Wilderness 2175 RB fiberglass vs. the Heartland Prowler 20P aluminum.
The two travel trailers are virtually identical in size and layout and features.
Single slide, 2 axles, 26' overall length.
Wilderness 2175 RB 4,648 lbs.
Prowler 20P 4,725 lbs.
In this case, aluminum or fiberglass is essentially the same dry weight.
