RV wall thickness can be affected by many factors. These include:

  • RV size, which affects wall weight, compressibility, and flexion.
  • The manufacturing process comprises framing, multiple construction layers, techniques, and codes.
  • Materials used include wall paneling, exterior walls, interior walls, studs, and insulation.

RV Size

RV Size, one of the critical factors affecting RV wall thickness, directly impacts the walls’ weight, compressibility, and flexion. The larger the RV, the thicker its borders should be to ensure structural integrity and safety. The size of an RV may be measured in length, width, or height, as well as overall weight.

A larger RV requires thicker walls due to increased weight load and structural demands. The weight of an RV also affects wall thickness requirements since a heavier chassis needs thicker walls for added support. Compressibility is another factor that affects sizes since larger vehicles require more stable materials that don’t compress easily over time.

Moreover, when it comes to flexion or bending stress on RV walls during travel or even parking on rough surfaces, larger rigs experience more flexion, rendering them prone to damage without an adequate wall thickness.

Interestingly, it’s worth noting that wall thickness doesn’t directly correlate with an RV’s gross vehicle weight rating (GVWR). GVWR only measures how much a vehicle can safely carry without risking structural damage and has little bearing on its overall size.

Sources confirm that as a rule of thumb for determining your needed wall thickness, the total height of your rig divided by 12 will yield your ideal minimum wall thickness in inches.

The RV manufacturing process is crucial in wall thickness and durability from framing to construction layers.

Manufacturing Process

RV wall thickness is heavily influenced by the manufacturing process used for constructing it. The method includes several techniques that vary according to the chosen materials and RV size.

Here is a table with some standard RV wall framing and construction techniques:

Technique Description
Stick-built Uses wood framing, fiberglass or aluminum siding, and foam insulation between the studs.
Laminated Uses an outer layer of fiberglass or other durable material, with foam insulation sandwiched between two layers of luan plywood or composite outer layers for extra strength and durability.
Vacuum bonded Similar to laminated construction, but includes a vacuum bonding method to ensure airtight and durable construction.
Welded aluminum frame Uses welded aluminum frames instead of wood frames, with aluminum exterior skin for strength and durability. Suitable for off-road vehicles.

The use of specific materials in the RV wall construction layers also affects its thickness. Generally, thicker walls provide greater strength and durability over time, making them preferable in harsh weather conditions.

Most importantly, codes regulate the manufacturing process to ensure that every finished RV unit meets some minimum safety and quality assurance requirements. These codes are implemented so that manufacturers follow specific recreational vehicle guidelines.

Historically most early RVs had wood frame sides. Fiberglass didn’t come into use until 1961 when fiberglass body Wilder Manufacturer made their first trailer called “Trailer Coach.”

RV wall paneling is the only thing separating you from the great outdoors (or your snoring neighbor).
