Welcome, Lois!
You're in the right place to learn about molded
fiberglass trailers.
They range from very small and basic, like my 13'
Scamp, to larger, fully-equipped units for full-time travel. You'll find that they're typically more compact and pricier than conventional framed trailers but have the advantages of lighter
weight, reduced maintenance, long-term durability, and high resale value.
I've owned conventional RV's before, and I'll never go back. Love my
Scamp: beds for four and a small galley in a 10'x6.5' cabin is a masterpiece of space utilization! It has appreciated in value since I bought it used four years ago, which was not true of any other RV I owned.
As you're shopping, be aware that molded
fiberglass manufacturers designate models by total length (i.e., a 16'
Scamp is 16' from tongue to bumper; the cabin is only about 13' long). Most conventional manufacturers designate models by cabin length. Helps when making comparisons.
If you give us some idea of what sort of trailer you're looking for, what kind of travel you anticipate, maybe some idea of your budget and intended tow vehicle, I'm sure you'll get some suggestions.
Best wishes in your "egg hunt"!
