What Is a Fiberglass Trailer?

Definition of a Fiberglass RV

A molded fiberglass RV is not a specific body type, like a Class A coach or a 5th wheel.

Instead, it’s a distinctive method of manufacturing.

Fiberglass trailers are from spray open-molded or cast closed-molded fiberglass fabrication processes. The camper bodies are assembled from just 1, 2, or 3 pieces.

The final assembled hull is lightweight, watertight, easy to clean, and very durable.

Classic fiberglass trailers are small travel trailers. However, you can get them in many different body types:

  • Travel trailers
  • Teardrop and mini campers
  • 5th wheels
  • Slide-in truck campers

Molded fiberglass campers are not available as motorhomes or coaches.

Unlike motorhomes like Class C motorhomes and conversion vans, you tow a fiberglass trailer. And no, you don’t generally need a special license to tow one!

Fiberglass RV Specifications

  • Lengths range from 10 to 25 feet, with 12 to 18 feet being the most common. 
  • Width ranges from 6 ft to 8 ft, with 6.5 to 7 feet being standard.
  • Height varies from 6 to 9.75 feet, with most ranging between 7 and 8.5 feet (rooftop A/C included).

Sleeping Capacity

Most fiberglass RVs can fit 1-6 sleepers (2-4 standard). You’d be surprised how roomy one of these campers is! They’re like clown cars.

Fiberglass RV Categories

Molded fiberglass campers are widely split into two/two subsets:

  • 1-piece/2-piece
  • Single-wall hull/double-wall hull

Single-piece molded fiberglass campers, like the Little Guy MyPod, are made using close-molded fiberglass casting processes. The body is one single, seamless piece – nor joints anywhere!

Most fiberglass campers are 2-piece designs, typically with a top and a bottom fastened at the mid-seam. This fabrication method is much easier to design, build and scale.

Also, most fiberglass campers have single-wall hulls. This means the wall is a single thick piece of fiberglass. There are no cavities for wiring or insulation.

A few RV manufacturers produce double-wall hulls. These are constructed more like boats than RVs! Essentially, an inner hull is nested inside an outer hull, like a Russian nesting doll. The space between is used for mechanicals and insulation.

Fiberglass RV Description

Most RVs are built using one of two types of construction:

  • Stick n’ tin
  • Laminated fiberglass

In both of these styles, the RV body is assembled from smaller pieces. In the example of a fiberglass laminate camper, the body is assembled from a subfloor, laminated walls, and either a cage roof or ceiling trusses, with a roof skin pulled over the top.

In contrast, a molded fiberglass camper is built like a plastic Easter Egg. 

Two fiberglass halves – usually a top and bottom – are molded using spray open-molded or cast close-molded fiberglass fabrication methods. Then, the two halves are fastened together to form a two-piece “hull.” 

Most fiberglass RVs, like Scamp, Nest by Airstream, and Casita, are small travel trailers. 

Fiberglass RV Chassis & Fuel Economy

Fiberglass campers have been popular since the 1970s. For one, they’re adorable! Secondly, they are small (fun-sized) and lightweight. The Scamp 13, for instance, has a dry weight as low as 1,200 pounds!

If you will be towing with a smaller towing vehicle, like a crossover SUV or compact pickup truck, a fiberglass travel trailer is a great choice. 

Virtually all molded fiberglass campers are built on custom chassis frames. Compared to conventional travel trailers, fiberglass campers are sold in low volumes, so every manufacturer designs and/or produces their own chassis.

Because these RVs have solid fiberglass campers, the usual mechanical innards in the RV underbelly, such as water tanks, are either mounted inside the unit or exposed to the road within the frame rails. Units with tanks inside the interior are 3.5-season campers and can be used in frigid temperatures; units with exposed water tanks cannot be fully used in winter.

Fuel economy will be based on the size and horsepower of your tow vehicle compared to the size and weight of your towable RV.

    • Average Fuel Economy loss, travel trailer: Expect 2-4+ mpg loss (the smaller the tow vehicle, the bigger the loss)
    • Average Fuel Economy loss, 5th wheel: Expect 3-6+ mpg loss (the smaller the tow vehicle, the bigger the loss)

Who Might Want a Fiberglass RV? 

People who like fiberglass RVs … loooove them.

Lightweight, maneuverable, waterproof, easy maintenance, good resale value – what’s not to love? They are easy to park, drive and store.

You might be surprised to learn how many campers live full-time in their egg-shaped fiberglass campers. No, they don’t have the lounge space or amenities of a Class A coach. And they can be claustrophobic after days of rain or snow. But they can go just about anywhere!

Fiberglass campers are a great fit for a person who enjoys minimalism and adventure. Most comfortably sleep 2, or 3 in a pinch. Some larger models, such as several Bigfoot campers, can sleep up to 4, or 5 in a pinch.

Most fiberglass RVs have bathrooms with a shower and toilet. The smallest have combined wet baths, but most, such as the travel trailers from Casita, have separated dry baths. 

Fiberglass RV Pros and Cons


  • Lightweight!
  • Easy to clean, inside and out.
  • Holds their resale value.
  • Waterproof, seamless exterior.
  • Aerodynamic, good for fuel efficiency.
  • Tow vehicle doubles as local transportation.
  • Lower profile allows easier entry than any other camper.
  • Can normally be stored in a garage or under a carport.


  • Limited interior lounge and storage space
  • Small refrigerators, cramped bathrooms
  • Limited to tents and awnings for living area expansion. No slide-outs.

Key Features in a Fiberglass RV

Model Type

The first decision is what style of RV do you want? Check out our other guides to RV model types to choose the style that’s best for you!

Size and Space

Let’s take a look at three common sizes of molded fiberglass travel trailers.

This is a layout from Scamp for its 13-foot travel trailer. Everything you need, nothing you don’t. Just a convertible dinette, kitchenette, storage, and wet bathroom. Great for one (or two travelers deeply in love).

If you want a little more space, why not check out this Casita 17-ft camper? It has a convertible dinette that can be left as a fixed full-size bed, a larger kitchen, and a dry bath. 

If you want the usual RV experience in a fiberglass package, you can checkout the 2500 Travel Trailer series from Bigfoot. This particular layout has dual twin beds, a 3/4 dry bath, full-size refrigerator, convertible dinette, and full-length wardrobe closets. If you’re considering traveling in your RV full-time, this could be a great choice!

4-Season or Not?

For some reason (don’t ask me), many buyers of fiberglass RVs are interested in winter camping or full-timing.

In fact, there’s a whole forum on the topic at

Brands like Oliver, Escape, and Bigfoot specialize in 3.5- or 4-season design. 

Sleeping and Seating Questions


  • What size of bed (twin, full, queen, short queen, king) do I need?
  • Am I going to sleep in the same bed as my partner, or will we need dual twin beds?
  • Can we scoot to the end of a bed, or do we need to roll off the side?
  • How much visual or acoustic privacy do we need? Will a curtain suffice, or a solid wall and a door?
  • Do we need a TV in our bedroom?
  • Do we need an adjacent master bath? 
  • Do we need a full-size bed for kids or guests, or will a murphy, sofa or bunk bed do the trick?


  • Where will we eat breakfast, lunch and dinner? Do we need a breakfast nook in addition to the main living area?
  • Do we need a separate table for office space?
  • How many people need to be able to watch TV or eat a meal at once?

Fiberglass RV FAQs


Of all RV types, fiberglass models may do the best in 24/7 exposure. Due to their lightweight, small strength and monocoque shell strength, they can handle rough conditions. Plus, you’re less likely to get bogged down in mud or sand!

However, most fiberglass RVs don’t have great ground clearance. You may need to flip the axle or add in lift blocks for rougher terrain.

Most of the appliances aboard a smaller fiberglass RV don’t draw as much power as their full-size equivalents. However, you may need to add additional propane tanks or upgrade your battery bank size to run off-grid for extended time periods.

No. Generally, you cannot “triple-tow” with a travel trailer. Even states that allow triple-towing generally do not allow it with a camper trailer because of maximum motorcade length and weight restrictions.

However, you can just use your tow vehicle as your daily driver!

Many fiberglass RVs can be towed with regular passenger cars! Some can be towed with vehicles rated for as little as 2,000 pounds, but most are best towed with CUVs, SUVs, or small pickup trucks rated for 3,500 pounds or more.
